Is The Trifield 100XE The Best EMF Meter?

Posted by Lloyd Burrell on December 7, 2010 under Electromagnetic protection, Trifield meter | 193 Comments to Read

Today I review the Trifield 100XE EMF Meter. I get lots of people contact me through my blog, some are just concerned about EMFs. Others are more than concerned they  already have symptoms of electrical sensitivity.

What people want to know is ‘how can I protect myself from something I can’t see’. My reply is always the same. To be able to protect you have to measure the threat. Here measuring the threat means evaluating the electromagnetic fields (EMFs) in your environment. Sounds tricky, but it’s not. The starting point is to measure with an EMF meter.

There are lots of EMF meters on the market, and I’ve tried many of them. Here I review the Trifield 100XE EMF Meter.

 

Why I Purchased the Trifield 100XE EMF Meter

– It’s so simple to use. All you have to do is turn the knob and read the dial. If the needle on the dial gives a reading on the broken read line on the dial your EMF readings are considered safe. If the needle goes over into a continuous read line you’re in the danger zone

– It’s excellent gaussmeter function. It can measure magnetic fields from as little as 0.2 mG right up to 100 mG! Few meters in this price bracket measure such a broad frequency range with such a high degree of sensitivity and accuracy.

– It can measure radiation from so many different sources; computer equipment, electrical wiring, electric ovens, TV’s, fluorescent lights…..even EMFs from transformers and power lines near the home

– I wanted a meter which could give me readings not just an EMF detector

– Its price.

 What To Look For When Buying An EMF Meter

The first thing to understand when you buy an EMF meter is that the electromagnetic spectrum is vast. Buying a meter which can measure everything is both impractical and extremely expensive (not to mention impossible).Trifield 100XE EMF Meter

But then you’re not interested in measuring everything. You’re only interested in the EMFs which have the biggest impact on your health. When you buy an EMF meter you need to buy one which can measure the EMFs which from a health point of view give us the most cause for concern. So you need a meter which measures :

–       AC magnetic fields

–       AC electric fields

–       Radio frequency/ microwave fields

Most EMF meters measure just one of these categories of EMF. The Trifield meter measures all three categories of EMF.

How To Measure Magnetic Fields

Just turn the knob on to the first “Magnetic” setting and then slowly start moving around your home or workplace. Magnetic field readings are given in milligauss. Magnetic fields can be found around devices like TV screens (older models tend to give off higher levels), clock radios, computer monitors/disk drives, electric typewriters, electric ovens and lots of other common appliances in your home, office and car… not to mention transformers and power lines near the home.

How To Measure Electric Fields

Turn the knob again and select “Electric” again work around your rooms slowly. Electric fields are measured in volts/meter.  Computer monitors, TV’s, fluorescent lights, improperly grounded electrical equipment, and electric blankets (especially if the polarity is reversed) – can give surprisingly high readings even when switched OFF if plugged in!

How To Measure Radio Frequency (RF) Radiation

Turn the knob again to the “Radio/Microwave” setting. This meter is perfect for testing for leaks and faulty doors seals on your microwave oven. My tests show even new microwave ovens often leak. A reading of 0.2 mW/cm2 at a distance of six feet would suggest a leaking door seal.On this setting the Trifield 100XE EMF meter can also measure cell and cordless phone radiation.

For more information on how to use the Trifield 100XE click here to download the full instruction manual.

What Sort Of Appliances Can I Test Around The Home?

You’ll be surprised at the dozens of appliances that give off EMFs around your home. Watch this video to see a demonstration of the Trifield giving EMF readings on 15 household appliances:

 

How Much Should You Expect To Pay For This Meter?

The Trifield 100XE EMF Meter is available on the Trifield website for $160. But you really shouldn’t be paying any more than $140 for this meter. The cheapest I have seen it is on Amazon.comwho consistently sell this meter for under $140.

This might seem a lot but if you’re just looking for cheap, cheap is what you’ll get. EMF meters on sale at $25 – $30 might look tempting but be sure to read the spec carefully before you buy – as with anything else you get what you pay for.

Does It Include Warranty?

Yes the Trifield 100XE EMF Meter includes a 1 year warranty.

What Do Others Say About It?

This meter has received rave customer reviews from people that have already bought it, with an average score of 4.5 out of 5 from reviewers on Amazon!

Here are some of the comments to date :

“It changed my behavior”

“A necessary device for health protection”

“Excellent Device”

“Might have saved my life!”

“Found lots of surprises”

“Every house needs this EMF test”

“A necessary device for health protection”

“High quality…easy to use!”

What Are The Complaints?

I’ve heard very few complaints about this meter. But don’t expect this meter to be what it’s not. It’s not, by any means the most accurate meter on the market for measuring EMFs – you can pay over a $1000 for a meter which only measures DC fields. And its certainly not the ideal choice if you’re wanting to measure cell tower radiation and WiFi radiation – better to buy a dedicated RF meter (see my reviews on the Acoustimeter and Cornet meters). But a meter which offers you the possibility of not just detecting but measuring 3 different categories of EMFs for under $140 is difficult to beat.

There are better meters out there. But I believe the Trifield 100XE EMF meter offers an unbelievable package of functions for the money.

Where Can You Buy This Meter?

You can buy this Trifield EMF Meter from Amazon.com.
At the moment they include free shipping and from what I can tell when comparing prices with other online retailers, Amazon do have the best deal for this meter.

EMF Meters – A Word Of Warning If You Live Outside The US

The EMF meters sold by Amazon.com are the 60Hz models which are calibrated for the American market. If you live in Europe or pretty much anywhere outside the US you need to buy a meter which is calibrated at 50Hz. So the meters being sold by Amazon.com will not work properly if you live outside the US. You can check what the electricity supply is in your country here. If you live outside the US you can buy a Trifield meter that will work in your country from this company.

Where Can I Read More Reviews?

The best place to go for reviews from people who actually use this meter is Amazon. Click here to read more reviews. The Trifield 100XE EMF meter is like having 3 EMF meters in one, and for that alone its hard to beat!

  • Liat said,

    I live in a place where power is measured according to European dimensions (I understand that Frequency of 50 Hz), I bought the TriField device which has Frequency of 60 Hz according to the U.S.
    Measurements for Magnetic radiation around my house shows very high results: 8-2 Milligauss. and the electric results shows 0.6-0.8 Milligauss.
    1. Is that OK?
    2. Will the Electric and the Magnetic affected by the U.S. frequency or only one, which?
    2. Is it possible to convert the measurements to fit the local terms?

  • Lloyd said,

    Hi Liat
    To answer your questions:
    1. On the back of your Trifield meter it says “above 3 milligauss of AC magnetic field and above 1 kilovolt/m of AC electric field – biological effects may begin to occur”. If you are getting magnetic readings of 8 this does sound high. You need to go around your home with your meter and identify the sources of magnetic radiation. The strength of magnetic radiation is directly proportional to the source of radiation, in other words the nearer you get to the source the higher your readings will be.
    2. If you are using a “US version” Trifield meter (which is calibrated to 60Hz) on a European power supply, which operates at 50Hz, you just multiply your readings by 1.17 to get true values (approximately). So for instance a magnetic reading of 8 milligauss on your meter would give a reading of 9.36 milligauss if it was properly calibrated.
    Hope this helps.

  • Dan said,

    Would this device be considered as a Geiger counter? We were looking for something that detects radiation.

  • Lloyd said,

    Hi Dan
    The Trifield EMF meter is calibrated to detect radiation relative to three types of EMFs, electric, magnetic and RF radiation. Nuclear radiation as given off by radioactive isotopes operates at a much higher frequency on the electromagnetic spectrum…..you can’t use the Trifield meter to detect this form of radiation.

  • deepika said,

    hi
    i am deepika,i stay in India i was going through mail and your mentioning about how to measure radiation using EMF meters and where we can get it,so, i stay in India if i want to order it on Amazon.com it would give me the same results in measurin cause you were talking about U.S 50hz and Europe more than 60hz if i buy it
    would that meter be working or giving me the same results cause affording to buy it is already a very big issue for me can i take chance please advice

  • Lloyd said,

    Hi Deepika

    There’s a link at the end of my article to a website with a list of electricity supply frequencies by country. It shows that India operates at 50Hz. If you were to buy a US version of the Trifield you multiply by 1.17 to get true values.

  • Dipak Sakle said,

    Hi,
    I need to know that is their any retailer of trifield meter in india so that we can directly by through them.

  • Lloyd said,

    India uses a 50Hz power supply like the UK (not surprisingly). This company ships to India http://www.radmeters.com/Trifield-100XE-fr.html

  • James said,

    Hi Lloyd,

    Thanks for sharing these information.

    I just bought a Ghost Meter only to realize it only measures magnetic field from 0 to 5 mGauss in a single direction. My main objective is to measure cell phone radiation and to test whether cell phone EMF shielding works. So now I am interested to order Trifield meter. Can you help me with some of my questions?

    1. Is Trifield meter good enough to measure cell phone radiation? (Because I see you in your video using a different device in black)

    2. Have you tested any cell phone EMF shielding sticker that works?

    3. My country uses 50Hz electricity and I intend to order 60Hz version due to lower price. Do I need to multiply the Electric field (V/m) and RF/Microwave reading by 1.17 too? If I measure for device not using household electricity (laptop on battery, in car, outdoor), do I need to adjust the value too?

    Thanks again.

  • Lloyd said,

    Hi James
    To answer your questions:
    1.For testing cell phone radiation in terms of value for money currently I do not think you can beat the Cornet ED85EX which I review here. The Trifield does measure RF radiation but not nearly as good as a dedicated RF meter like the Cornet.
    2. I have tested lots of EMF chips, there is not one I can recommend.
    3.No need to multiply the RF readings by 1.17, they will be the same regardless of what country you are in.

  • VBDF said,

    HOW SAFE ARE A/V SENDER RECEIVERS? I ASK BECAUSE THESE DEVICES CAN RUN NON STOP IN SOME HOUSEHOLDS (FOR EG. BROADCASTING PAY TV TO A SECOND TV)

  • Lloyd said,

    These devices emit RF radiation just like a cell phone or cordless phone. Older versions tend to use analog signals on the 2.4GHz frequency band but more recent versions are on the 5.8GHz frequency band and are digital – so they emit pulsed radiation. If you do have one of these devices make sure you unplug it at night.

  • Zaidoun said,

    Hi, I’m trying go figure out if the Trifield is an appropriate meter to measure emf from a substation and if you know of any special instructions to measure this properly.
    Also on Amazon reviews i saw a review about this measuring higher than reality, your experience?
    Thanks

  • Lloyd said,

    The substation will develop both electric fields and magnetic fields. The strength of the electric field is dependent on the voltage but they are unlikely to extend beyond the installation. The magnetic fields are a different story. The larger the substation the higher the magnetic fields and pretty much nothing will stop them, they even travel through walls. The Trifield can measure these magnetic fields perfectly well. It might not give you a bang on accurate reading, but you won’t need this for what you are doing. To take your measurements just select the magnetic range on the Trifields selector dial (set it on the 0-100 range to start with), and watch what the needle does.

  • Pat said,

    We recently had a smart meter installed at our house by our electric company and I am concerned about its radiation. I understand that it uses RF to transmit the meter readings to a central computer. Will the Trifield meter register the smart meter radiation?

  • Lloyd said,

    This Trifield meter is unlikely to give you any reliable readings of smart meter radiation- it is not sufficiently sensitive. You need a good quality dedicated RF meter for that e.g. the Cornet ED85EX

  • steve said,

    Do you see any additional value in the triefield extended range broadband meter. I am taking your advice about the cornet, but am not sure about which trifield to buy.

    Thanks.

  • Lloyd said,

    I can’t really see the benefit of the extended range meter. The improvements (better magnetic field and RF sensitivity) are not significant. In terms of RF measurement for instance, it’s still limited to 2.5Ghz – better to buy a dedicated RF meter.

  • steve said,

    Lloyd,

    Thank you. I also contacted a vendor (not trifield) and received the following, which supports your comment. Note the reference to the RF sensitivity which is in line with your comment for the need for a CORNET meter for RF. i.e. The Trifield is really only good for detecting strong RF signals.

    “The Trifield Broadband has an extended range for RF only. For ELF it is the same as the regular version. Since the Trifield is not good for environmental RF measuring due to its low sensitivity, it wouldn’t help. Moreover, the Broadband RF sensitivity is worse than the regular Trifield. To place things in proportion, here is an example. The lowest standard in the world at the moment is 1 mW/m2 (MilliWatts per Meter square). The Trifield RF sensitivity starts at 100 mW/m2 and the Trifield Broadband starts at 270 mW/m2.”

  • David said,

    Hi Lloyd, Is the Trifield 100XE good for measuring radiations from cell phone towers? How does it compare to the Trifield Natural EM Meter or the Cornet ED85EX?
    Thanks

  • Lloyd said,

    The Trifield Natural EM Meter is not best suited to measure cell tower radiation. It has the same limited RF frequency range as the Trifield 100XE. A dedicated RF meter like the Cornet ED85EX or the Acoustimeter AM-10 will give you far more accurate readings.

  • Mark said,

    Hi Loyd, I will have to get one of these meters I think.

    Just a couple of quick questions please. At my work place they have recently installed a 42 inch LCD television screen which is no more than 15 inches from my head (at my right side and back at a 45 degree angle). The bottom of the screen is perhaps a foot above the top of my head as I’m seated. I’m facing away from the screen (as this is a customer display for promotions). I sit here for up to 8 hours a day, 5 days a week. Is this likely to be giving me dangerous EMF levels?

    Also, do the Q-LINK pedants actually help, are they a solution if I cannot move desks, as this is where I’ve been placed?

    Thanks

  • Lloyd said,

    Hi Mark
    Yes, this will be exposing you to EMFs, it’s impossible to tell if they will be “dangerous”.

    First thing is to try and negotiate with your boss, find an arrangement where you can sit at a safe distance, at least some of the day (ideally about 6 feet), explain the dangers of EMFs to him/her (you could print out some of the information from this website), if you have a Trifield meter show him the readings, if you don’t have one, consider buying one (though not essential).

    Secondly work on reducing your EMF exposure elsewhere in your life (for me the Q-link is not a solution to the EMF problem), it may be that the LCD is not your biggest source of EMF exposure, subscribe to my newsletter for tips on how to do this.

  • Patrick said,

    Hi Lloyd,

    I conduct EMF readings through my westernfengshui business here in the Twin Cities. I’m currently using a “Cell Sensor” for all of my EMF readings. Is this one of the more sensitive and accurate readers on the market? If not which would you recommend for testing appliances, electronics and so forth?

    I’m also curious to know about the laptop that I’m using.
    It registers off the freaking chart! Is this a common issue with laptops? If so, is there a brand that you can recommend that has addressed this issue?

    Thanks much

  • Lloyd said,

    I have not tested the Cell Sensor so I can’t comment on it. The meters I recommend, all shown and reviewed in depth on my website, have good accuracy and sensitivity for the money. The cheapest combination would be to buy the Trifield with the Cornet to be able to measure across the spectrum.
    I personally use a desktop PC…..to date I have not found a low EMF laptop.

  • Paul said,

    We have had unexplained illnesses in our house for several years. We did the mold testing and that was negative. We bought the recommended TriField Meter and it showed that the underground utilities buried on our property were putting out a field that read between 25 and 100 on the meter. We are trying to find a solution to this problem. So far the city utitlity has not agreed that there is any problem.

  • Patrick said,

    Paul’s question beat mine to the punch. I was also wondering about readily available construction materials that could be used to shield residential/commercial buildings or specific areas from EMFs. My first choice would be a product such as “Reflectix”. It consists of 1/4″ thick bubble wrap, sandwiched between two thin and very flexible sheets of aluminum. It’s typically used for insulating irregularly shaped walls or cavities, where standard fiberglass batting is inconvenient or susceptible to contact.
    Wouldn’t this be an ideal product that could be wrapped around the electrical piping/conduit to contain the EMFs? It’s available in 18″ – 48″ wide rolls x 25 feet long. What’s your take on this Lloyd?

  • Lloyd said,

    There are lots of materials now on the market that are suitable for EMF shielding. Apart from saying Reflectix looks a good product, I can’t comment because I have not tested these products (it may be cheaper to buy a shielded conduit).I will be writing a detailed review of shielding products in the coming weeks. You might want to subscribe to my newsletter if you want to follow this.

  • Jamie said,

    Is this meter a good choice fir measuring local cell towers? Is the meters range sufficient to pick up indoor wireless routers to residential 4G towers?

  • Lloyd said,

    No, you need to buy a dedicated RF meter for this purpose – see my reply to David above.

  • Alex said,

    Hi!
    Have you noticed that the Trifield meter 100XE sometimes may give higher reading than it really is ?
    What do you think about the fact that it can detect signals up to 100 Khz, which is not typic for a household?

  • Lloyd said,

    The Trifield has its limitations (in terms of precision and accuracy), but inspite of these limitations I believe it has a role to play in EMF mitigation. In theory being able to detect up to 100 Khz is a plus ( dirty electricity is in this frequency range) but in practice, I am not sure this information would be sufficiently accurate to act upon, better to purchase a GS meter for this purpose or a high end ELF meter.

  • harry said,

    Is the Trifield 100XE suitable for measuring high voltage tower lines? Very helpful information Lloyd, thank you.

  • Lloyd said,

    The Trifield 100XE is suited to measuring EMFs from high voltage powerlines. The principle is the same as for any electric wire (50hz in Europe, 60hz in United States), except the voltages are higher….you will be able to measure both electric and magnetic fields from the powerline with a Trifield.

  • Jesse said,

    Hello Lloyd,
    My Trifield just arrived I would like to ask you something about the meter please, when I switch the knob from the magnetic range 0-100 to 0-3 makes big spikes & the needle hit the lateral of the screen very hard, is that ok? Could this affect the calibration of the meter in the future?
    Thanks.
    Jesse.

  • Lloyd said,

    Hi Jesse
    1. For your health, if you are in an environment where you are obtaining readings in excess of 3mG, you do not want to be spending long periods of time (Bioinitiative safe limit is 2mG, http://www.electricsense.com/2951/bioinitiative-report-on-electromagnetic-field-emf-dangers/) 2. Avoid using the Trifield on the 0-3 scale if you are getting readings over 3mG on the 0-100 scale, you could damage it.

  • Jesse said,

    Hi Lloyd,
    Thanks a lot, I am going to get very soon a Cornet to test it out RF the Trifield is not very good at RF.
    One question please, Would affect the emf to the storage food & then eat it?
    Thanks
    Jesse

  • Lloyd said,

    Hi Jesse
    Exposing food to EMFs is harmful and even dangerous. The research done on microwave ovens confirms this, see http://www.electricsense.com/241/electromagnetic-fields-and-microwave-ovens/

  • Jesse said,

    Thanks a lot Lloyd, I have few spots of EMF radiation in my house I´ll try to keep away from those spots,also my food.
    For RF at what level we should start to worry about?

  • Lloyd said,

    Hi Jesse
    For RF radiation I recommend following the Bioinitiative report guidelines: 0.1 μW/cm2 ( 0.61 Volts/meter) for outdoor exposure and a limit of 0.01 μW/cm2 ( 0.19 Volts/meter) for indoor exposure, see http://www.electricsense.com/2951/bioinitiative-report-on-electromagnetic-field-emf-dangers/

  • Jesse said,

    Thanks Lloyd,
    I have one big spot at home tested very closely on LF 439mG crazy meassure, isn´t? then at 50 cm from this spot doesn´t give me anything tested with the Cornet(on LF) & also with the Trifield, Should I trust them? I have a pic of it if you want it.
    I did have others problems on RF specially with my wireless telephones I have choked them out in the bin already,the RF figures of wireless (Base)with my Cornet they are even higher than ones tested on the mobiles phones!!!!
    Also the light(Lamp) of my work room was very bad gave to me a very high on Electric radiation so I have bought a led light, this one looks very good at least in what I can test at the moment… RF,LF & Electric.
    I have no words to thank you for all & I hope that I recover myself soon from all my sicknes.

  • Lloyd said,

    Hi Jesse
    The best thing to do when you are getting unbelievably high readings with your meter is test with another meter. You’ve done this. As I understand it both meters are giving high magnetic field readings (the Trifield only measures to 100mG) so this does suggest the presence of high magnetic fields. What is strange is that the readings fall off so quickly? There must be something causing these readings…wiring faults or a high voltage power lines are the first things that come to mind. In any case I would strongly recommend not spending any significant amount of time in the room where these fields exist. I’d be interested to know what could be causing such high readings.

  • Jesse said,

    Hi Lloyd,
    That high reading is from a source of cable internet in my living room , very extrange thing, isn´t? but at 50 or 60 cm doesn´t meassure anything, could we be at dangerous inside that room? For example on the sofa area where we sit to watch tv doesn´t read anything with both meters Trifield & Cornet.
    Thanks a lot for your help.

  • Jesse said,

    could be maybe tv anthena amplifier?
    Thanks

  • Lloyd said,

    Hi Jesse
    If it’s the TV antenna amplifier that is causing these high magnetic field readings then the nearer you get to it (the source) the higher your readings should go. In any case what important is to minimize your exposure, if both your meters are showing zero/negligible exposure levels on your sofa these readings are not a cause for concern.

  • Jesse said,

    Thanks a lot Lloyd for your advice.
    Good Luck with your book!!!! Great!!! Thanks again to share with us your knowlege.

  • Jesse said,

    Is it true what people said? is it difficult the battery replacement on the Trifield?
    I didn´t open mine yet also I am not very handy person…

  • Lloyd said,

    To access the battery you just unscrew the 4 little screws on the back panel and slide off the cover, it’s very simple. The meter works on a standard 9-volt rectangular battery. You get about 10 hours continuous use on a standard battery and 30 hours use on an alkaline one according to the manufacturers.

  • Jesse said,

    Thanks Lloyd

  • AC said,

    So Lloyd, what is the main difference between getting one calibrated to 50Hz v. 60Hz? Will either one function in any environment, only causing some difference in reading ratio? What if I use a Trifield Meter that is calibrated to 50Hz in the US? Will it be able to function properly with just a small difference in reading that I would be able to calculate?

  • Lloyd said,

    According to the manufacturers the Trifield 50 and 60Hz models are the same meters which are calibrated differently. If you are using a “European version” Trifield meter (which is calibrated to 50Hz) on a US power supply, which operates at 60Hz, you divide your readings (Magnetic and Electric field) by 1.17.

  • Adam said,

    Hi Lloyd,

    I have a quick question. I just got the TriField and the house I’ve been staying in has HUGE magnetic fields (25-100+ mg everywhere), but most of it shows no electric field, at all. I don’t know where it’s coming from. I’m curious, though, as to the health significance, when you have the “magnetic” field but not the “electric” field?

    Also, I found out the place I was sleeping had a magnetic field of about 40 and an electric field of 3. No good. I’ve been dealing with some pretty debilitating health problems. Does sleeping in an EMF field like that cause permanent damage? Are we talking years of exposure, or even months? I’ve only been here for 2 months and I’m moving, but my health and stress-related symptoms got much worse after moving here. When we talk about EMF and cancer, etc, are we talking about years of exposure or…? Thanks for your time!

  • Lloyd said,

    Hi Adam
    We don’t know how much EMF exposure leads to damage because there are too many variables. Magnetic fields are particularly dangerous in the sense that virtually nothing can stop them, they travel through walls, ceilings, concrete, most metals….The readings you are getting are high and it is likely/possible that your symptoms are related to this exposure. The good news is your body can recover…given the chance. I suggest you move out as soon as you can.

  • Banks said,

    Hi Lloyd
    I just bought the trifield Model 100 XE and the rseults for my office cabin where I sit are shocking. The magnetic reading shows above 100 milligaus (There is an electric meter room behind the wall of my cabin). Readings in the other areas of my entire office are normal. Would appreciate if you could suggest any way in which my cabin can be shilded from this radiation. Also, how is magnetic radiation harmful for humans?

  • Lloyd said,

    Hi Banks
    Shielding from magnetic fields is difficult and costly. Magnetic shields work by redirecting the magnetic fields, not by blocking them. You need specialized materials to achieve this. Giron, for instance, is a magnetic shielding film which can be shaped without it losing its shielding properties. Mumetal and other specialized materials are commonly used but they can’t be worked with quite as easily. The problem with both these materials is that they are quite expensive, see LessEMF website. Iron is a cheaper alternative. It might do the job – use a piece which is not ferromagnetic (magnetized). For your solution to be 100% effective you would need to enclose the field source, in this case your electric meter room…not very practical. For most people the easiest is to move away from the source…change offices.

  • Eddie Brevo said,

    Hi Lloyd,

    Thanks for supplying such a wonderful site and Im new here. I just stumbled across your site when searching for EMF related questions. I started to become more aware of the satellite dishes everywhere on buildings, apartments, etc. Its everywhere here in NYC and I never payed attention until someone mentioned it to me. As a parent, im concerned and it seems I will be purchasing the Trifield 100 XE as it sounds great along with its multi-purpose uses. I just read another comment here about the Cornet ED85EX you mentioned. Here are my questions:

    1.Im assuming the Trifield 100 XE can read my cell phones radiation levels as well?
    2.Any difference between these 2 since I would like to find out about my cell phone figures as well.

    Thanks again for all your help!

    Eddie from NYC

  • Lloyd said,

    Hi Eddie
    You need a dedicated RF meter to measure cell phone radiation…depending on your budget…one of the Cornet meters (see http://www.electricsense.com/category/emf-meters/cornet-meter-emf-meters/) or the Acoustimeter are all good choices.

  • Eddie Brevo said,

    Thanks very much Lloyd. I will definitely look into the Trifield 100 XE and for sure the Cornet as you recommended.

  • Anita said,

    Lloyd,

    I am interested in purchasing the Trifield 100XE.

    My first question is, in your opinion is this still the best meter for measuring lower EMF emissions. I noticed your review post about the Trifield meter was in 2010 and didn’t know if there may be a better meter on the market now.

    My second question is that I checked Amazon and it is currently listed for $117.00, however, it does not state what upgrades it comes with for this price or if a carrying case is included. The Alpha Lab website, however, lists the Trifleld for $160.00, but then gives you all upgrades to select for additional cost. My question is…are any of these upgrades important and/or necessary. I don’t really know what I am assessing here.

    Thank you :)

    Anita

    P.S. I also plan on purchasing the Accoustameter for RF readings.

    Hi Anita
    Sure there are better meters on the market than the Trifield 100XE, but for the money if you want to measure electric and magnetic fields this meter offers unbeatable value. The Amazon website just sells the meter which as you say the Alphalabs website is selling the same meter with the same spec for $160. I checked the list of upgrades – I’d just go for the basic meter.

    I need to investigate what it could be a beginning of Electrical Sensitivity . I just run into your site and read a good chunk of it , it’s clear that the first step in searching for possible problems inside my house it’s to get a EMF meter. I am considering this above,do you think is it worth to have a dedicated RF meter together with this?

  • Lloyd said,

    Hi Massimo
    The ideal set up is the Trifield 100XE and a dedicated RF meter (and then a GS meter), see my reviews on these. Start by buying one meter, see how you get on with it for a few days and then move onto buying the next one. All the companies I link to are reputable dealers who will give you a refund no questions asked if you are not happy with your purchase.

  • Anita said,

    Thank you very much for your response, Lloyd. I have one more question.

    There is another Trifield meter called the Trifield Broadband meter that offers an extended sensitivity down to 5Hz. I am sensitive to EMF fields and wonder if the ability to measure these even lower frequencies would benefit me over the XE100 Trifield model. Do you know anything about that meter?

    As I mentioned previously, I will also be purchasing the Accoutimeter. I don’t know much about EMF equipment and will have a learning curve when I buy them. I am trying not to purchase more than what I need or end up paying more for duplicate coverage, but in the same turn, I intend to keep and use this equipment for a very long time and want to be sure I am buying what I need.

    Thanks again for your help!

    Anita

  • Lloyd said,

    Hi Anita

    The Trifield BroadBand Meter is a version of the Trifield 100XE which has a modified radio frequency section. It measures in the range 0.1 MHz – 50 MHz which the standard Trifield doesn’t. But its still limited to 2.5Ghz. Better to buy a dedicated RF meter.

  • Massimo said,

    Thanks Lloyd for your help.

  • Mark Penberthy said,

    Hi Lloyd, I just purchased the Trifield 100X meter and then discovered your review. Ideally, perhaps a little backwards, but I agree with your assessment that it’s an excellent overall household EMR meter. I have a question, however. By any chance do you know if there’s a correlation on the radio/microwave meter setting between the solid red line (danger zone) as measured at 0.1 mW/cm2 and the FCC maximum SAR limit of 1.6 W/kg? Any information would be greatly appreciated. Regards, Mark

  • Lloyd said,

    Hi Mark
    SAR is a measure of exposure (supposedly) whereas what you are seeing on your Trifield is a measure of signal strength…..the higher the signal strength the higher the exposure – depends on other factors also, e.g. proximity to the source. That’s the simple explanation. Read this paper for a more complete answer http://www.electricsense.com/wp-content/uploads/2013/01/07.11052005.pdf

  • Stephanie said,

    Hi, LLoyd. I used the Trifield today to measure the EMFs in a new hybrid car that i purchased last week and have been having symptoms from driving. The meter showed readings at the very end of the spectrium, well past the 100 top number. These numbers were recorded at the driver’s foot and at the passenger seat and almost that high on the rear seat. Of course there is no way to know how high above 100 the EMF’s are as the meter doesn’t record that much but I’m very concerned and want to show these findings to the dealer. Do people report such high findings in their hybrid vehicles? At what level are these readings comparable to x-rays?

  • Lloyd said,

    Hi Stephanie
    Other readers have contacted me saying the same thing about the EMFs from their Hybrid. Your Trifield meter measures RF, magnetic and electrical fields. This is classified as non-ionizing radiation where as x-rays are ionizing radiation….its more dangerous. But the readings you are getting are high and dangerous – the BioInitiative report details adverse health effects at levels as low as a few mG.

  • Mark Penberthy said,

    Hi Lloyd,

    Thanks for the response and link to the article.

    Regards, Mark

  • Eva said,

    From Amazon reviews…

    There are two or three versions of this instruments. This one provides 2 to 4 times the actual measurements.

    Its measurements are too high when compared to other professional instruments. There are two or three versions of this device that are available, you have to be aware which one provides the measured numbers versus providing the weighted levels which are usually two to four times higher in one of its versions.

    Can you clarify weighted vs measured?

    thanks so much,

    Eva

  • Lloyd said,

    Hi Eva
    An EMF meter that gives you a reading is making a series of judgments to give you that reading….there’s nothing ‘absolute’ about these readings. In simple terms weighted or non-weighted just means these judgments are made with a view to communicating different information. A non-frequency weighted meter is set up to give a flat reading….which is misleading if you are concerned with the effects of these EMF exposures. And misleading if you are not able to interpret the information (i.e. a professional) Most EMF meters are frequency-weighted. Its about giving a reading that reflects what the human body would experience. The Trifield 100XE gives a weighted reading from 40 Hz to 500 Hz…..50/60 hertz is the frequency found in most homes.

  • Mark Nicholson said,

    I have the TriField Broadband Meter and when I set it to Electric and get near almost any appliance in my house that is plugged in the needle goes almost all the way to the right. What does this mean and what do I need to do? Someone recently installed several dimmer switches in my house. Could that be contributing? Do I have dirty electricity? Help!

  • Lloyd said,

    Hi Mark
    There are different versions of the Trifield, I’m familiar with the Trifield 100XE- if your questions relates to this meter I’d be happy to help…in which case I need more specifics…at what distance…next to what appliance/s….what reading exactly?

  • Sue said,

    Hi Lloyd

    I have the original Trifield meter. You reviewed the Trifield 100XE which has an electrical range sensitivity increased by 100 times over the original meter, according to the manufacturer. The magnetic and radio/microwave ranges remain equal on both the original and the 100XE meters.

    I’m considering whether or not to upgrade to the 100XE. Can you see reasons for upgrading?

    Are there any other ELF meters you’ve tried that you think are great?

    Thanks.

  • Lloyd said,

    Hi Sue
    The 100XE is a very good meter for the price…I can’t compare it to the meter you already have because I’ve not tested it. The other meter which is similar is the CornetED75…it depends what you are looking for…you just need to read the reviews and compare.

  • Jon said,

    Hi Lloyd

    Stumbled upon your site while researching on the dangers of EMF exposure in households. Highly informative web page you have, truly a gem for those searching for EMF radiation info.

    Anyway, I’ve got some questions. I plan to buy a Trifield EMF meter to monitor electric and magnetic fields around my house. Some details about where I live:
    1. There are high voltage high tension cables approx 30 metres (100 feet) away
    2. There is a electric substation approx 15 metres (50 feet)

    Based on this, and until I get an EMF meter to test, what are your thoughts on dangers of exposure to EMF from these two sources? I know its impossible to give a good guess estimate, but this question has been itching on me for days.

    Also if, and upon confirmation with an EMF meter, there are dangerously high EMF readings around my home, how best can I reduce or even, eliminate these radiation from those 2 sources? I’ve read from posts above that magnetic fields are difficult to reflect? What options are there? (Sorry im not an electrical engineer)

    Appreciate greatly your input. Thanks!

  • Lloyd said,

    Hi Jon
    Whether the high voltage cables or electric substation are a source of high EMFs for your home will depend on the voltages and current involved…only an EMF meter can tell you if these dangers are real or not. The 100XE meter is adequate for this kind of work…see what readings you get….then look at the solutions.

  • Sue said,

    Hi Lloyd,

    Thanks for your reply. I’m electrically sensitive to my laptop’s audio, so keep the audio turned off. I can’t always see the meter range you are using in the video and don’t hear what you say, even though you probably explain it quite well

    I am wondering, what do you use the electric range on your 100XE model for?

    What specific devices or things have you personally measured with it?

    Thanks

  • Lloyd said,

    Hi Sue
    You should check all your electrical appliances and electrical wiring for electric fields…which is what I did when I bought my meter. My videos are not perfect…I know.

    Hello,
    While trying to research on posible health effects of wifi…(had health problems start about same time as getting cell phone and wifi, but also found later a roof leaf(hidden) so mold. now roof repaired and mold removed.
    Onto SCD diet(real food), has helped much. My son laughed at idea of sensitive to EMF. Did your questionaire and 3 yes’s(computer ~3 hrs/day, other son has wifi and see many other houses nearby show high on my computer list.
    Mostly worried about wifi , which have learned from your site is RF , so need a meter that tests that. Did have electric company test our house last year. Rooms were about 2mG and was amazed how hi blender… even natural spectrum flourecnt table lamp.
    2 mths ago a smart meter was installed but at least its
    far from bedrooms(street side of garage).
    found some meters on web and wondered what #’s should I look for in range of posible measesurement? one for $60 on amazon -wide range: 0.1-199.9 mG; 0.01-19.99 microT
    accuracy: 4% ±3 digits at 50/60 Hz,even 1 for $6. A gaussmaster for 35-Two scales: 0-1 mG and 0-10 mG,AC Magnetic, 40-2000Hz. Are these even posibly worth getting?
    Have 3 volt meters and wondered how to use these for checking EMF around the house. Would really be nice for brain to work better (getting worse when take public trans.,maybe their free wifi)
    Thank you so much for making all this EMF,RF,LF… more understandable
    Lynn D

  • Lloyd said,

    Hi Lynn
    You are right to look at the bigger picture in dealing with your sensitivity, see http://www.electricsense.com/4210/beating-electrical-sensitivity-part-1/ As regards the meters, there are some very cheap meters but my experience is you get what you pay for. The meters I recommend are here http://www.electricsense.com/category/emf-meters/

  • Lynn D said,

    Forgot to ask if you have every tried covering router
    w old cooking pot to see if might reduce exposure(my son sleeps near it and wont turn it off yet as it then gives lots of problem for computer later, his work is digital art).
    Also heard of Geostress, have you known experience with this? We have a house with 1 part very cold, neighbor cats sleep outside room (heard they are attracted to geostress).
    Thanks and be well
    Lynn D

  • Lloyd said,

    Obstructing the signal on your router could make your router work harder/cause a fire. Better to disconnect it at the wall when you are not using it.
    Harmful EMFs can be present in our environment emanating from natural sources – commonly called geopathic stress. These can cause all sorts of health issues…Dr. Richard Gerber talks about this in his book Vibrational Medicine.

  • Lynn D said,

    Lloyd,

    Thank you for your response. I actually read that book about 10 yrs ago(trying to track health problems , found we had CO leak in heater).will check it out again.
    The router is next to sons bed,its wired to his computer but my computer recieves pings from it. Want to get a meter to check where in house we get wifi from it and neighbors and show him readings to see if he’s willing to change it. He wont unplug it as really messes up computer trying to turn it back on. Maybe I will purchase 1 that can be turned off. and build myself a faraday cage around bed(will see if Al screen is conductive).
    Will check on wifi meters for now.
    I am doing fairley well, have gained strength,energy,brain power,but need more. Juicing has also been beneficial to absorb needed nutrients.
    Thanks again and be well.

  • claude said,

    I am 85 and have just purchased the Trifield 100xe and have found in my bedroom reading that maximize on the meter. A Smart meter has been put in 2 months ago on the garage level, I sleep on 3rd floor of the same wall. The meter goes to the far right on the floor and in the ceiling downstairs. We are now sleeping in the living room where the level is zero. What to do? I also have runny nose in many parts of the house especially the kitchen…

  • Lloyd said,

    Can you tell me
    – what setting the Trifield is on when you get these high readings (there are 4 settings on this meter)? – I need the exact setting
    – what readings you get? is the needle jammed over to the right…or is there a reading?
    – are the readings the same all over the room?

  • Sue said,

    Hi Lynn

    Re: router wifi – as far as I know, every company who provides what is called “a software switch” which the user can access through their computer to turn off wifi without unplugging the router.

    If you still keep wifi, you should be able to at least disable it each night and enable it in the morning. To find out more about this option, call your internet service provider and ask to be connected to technical support. They can guide you through the process of disabling the wifi. Normally a password is needed for this. If you don’t have one, they will help you through the process of getting one.

  • Lloyd said,

    Most routers can be disabled via the software but unless you actually test with an RF meter you can’t be sure whether your router is still disabled…software updates are ongoing for these devices and many are configured to reactivate the WiFi function upon receiving an update…they revert to factory settings….switching off electrically avoids this problem.

  • Sue said,

    Hi Lloyd,

    “software updates are ongoing for these devices and many are configured to reactivate the WiFi function upon receiving an update”

    Very interesting. Thanks for the heads up.

    “Most routers can be disabled via the software but unless you actually test with an RF meter you can’t be sure whether your router is still disabled”

    You can also use an iPod which is more common to have than an RF meter. The iPod shows the router model number. Like Comcast would be Belkin 133 or something like that. So if you know your model, you can spot it immediately.

    And the iPod signal-strength bar display would most likely indicate close to, if not the maximum, next to your model number because you are in close proximity to it. Wifi signals coming from the neighborhood are less than maximum because of the distance between you and them. So even if you don’t know your model number, a high strength signal display would be a good indication.

    “switching off electrically avoids this problem.”

    Yes, if it can be done.

  • claude said,

    Hi Lloyd, the meter is on the first Magnetic setting after Battery Test. It goes past 3 to the high level about a foot and a half from the floor all around the bed and in the NW corner of the wall. The smart meter is 3 floors lower at the garage.
    The room directly below is my TV room with my chair against the wall where the back of the refrigerator is and the meter goes up to past 3 when it is on.
    The ceiling of this room is the one below the high floor reading and read in a similar fashion. The NW corner where the Smart Meter maximizes over 3.

  • Lloyd said,

    Hi Claude
    These readings are high but I think your smart meter is a red herring here. Smart meters emit principally RF radiation, your Trifield is picking up magnetic radiation…this sounds more like an electrical fault…could be faulty wiring in your home or the refrigerator itself. Unplug the fridge and retest again, if you’re still getting high readings you need to get an electrician in to look at this…explain your problem over the phone…ask for a written quote before getting any work done.

  • David said,

    Hi Lloyd,

    I just received my TriField meter. Please explain the 0-3 magnetic measurement. When I have it on 0-100 it reads only 2. However- when I put it onto the more sensitive 0-3 range it goes to very high range. Which magnetic one should one be concerned with.Thanks David

  • Lloyd said,

    Hi David
    If your readings are are above 3 mG you need to be on the 0-100 range, the top scale, if they are below 3 mG you need to be on the 0-3 range for better accuracy, the middle scale on the meter. When you put it on the 0-100 range you lose some accuracy, hence the slightly different reading.

  • David said,

    Thanks!

  • Sofia said,

    Hi Lloyd and thank you so much for this site and all your information. I have symptoms such as brain fog, trembling, fatigue, blood sugar problems, heart palpitations, etc. It’s getting worse and I only recently realized it could have something to do with EMF. So I’m totally new to this.

    I have condo neighbors with wifi (I turned mine off a few days ago) and a cell tower close by and some neighbors around have smartmeters. I also want to measure appliances and such at home. After reading on your web-site I decided to get the trifield and the Cornet ED85EX.

    Since the ED85EX was replaced, I ended up ordering the ED78S (ordered it today). Do you know if it will do what the ED85EX does – is it as sensitive? I assume I still need the trifield, correct?

    Forgive me if you have already covered this – I can only be at the computer for a few minutes at a time lately… thank you so much.

  • Lloyd said,

    Hi Sofia
    The Cornet ED78S is as sensitive as the ED85EX but it has a slightly narrower frequency range (‘100MHz to 8GHz’ compared to ‘1MHz to 8GHz’ for the ED85EX’)….smart meter and cell phone radiation are in the GHz range….so not really an issue. But neither of these meters measure electric fields….which the Trifield does.

  • Sofia said,

    Thank you so much! I will get the Trifield as well then. Thank you!!

  • Steve said,

    Hi Lloyd,

    I just tried to purchase this meter from Amazon.com but they couldn’t process the order for outside of the US. Do you have any other links for this meter at the same amazon price? It is pretty expensive elsewhere.

    Also while I am here, I am on a candida diet at the moment and when I take natural anti fungals ie garlic I have the same sensation as when I feel EMF’s. Is there a correlation with candida and EHS?

    Thank you,

    Steve.

  • Lloyd said,

    Hi Steve
    You can also buy the meter through Radmeters, see http://www.radmeters.com/Trifield-100XE-fr.html
    I’ve no doubt that your body’s overproduction of candida, the foods you eat and your ES symptoms are linked. Everything you eat and drink has a bearing on your ES. Tending towards an alkaline diet should help your candida and your ES.

  • Steve said,

    Thank you Lloyd,

    With your book and applying your advice I have managed to get my symptoms under control whilst in a “safe” place. So hopefully the healing can start to take place now and sometime in the near future my body will be able to tolerate some EMF’s so that I can live a “normal” life.

    Do you live a “normal” life now?

    I heard someone quote that 60% of people can heal themselves of EHS symptoms and 40% can improve their condition. What is your opinion of this?

    I am keen to get better and implementing what you have suggested, what I like about your program is that you are very positive in overcoming EHS and I am looking forward to the “tipping” point! Already my health is the best it has been for a long time and energy levels are also increasing.

    Thanks again LLoyd you are doing awesome work for people in distress with EHS!!

    Steve.

  • Steve said,

    Also I got this reply from radmeters would you still recommend the 100xe or the flat?

    Dear Steve,
    Thank you for contacting us. There are actually 3 models for the Trifield 100XE, 50Hz, 60Hz and Flat. We usually recommend the Flat version over the 50Hz or 60Hz versions. The difference between them is the way they show the result when different harmonics are present. For example, if you measure a 50Hz source which emits 10mG, both the 50Hz and the Flat will show 10mG. But if you measure something with a 100Hz for example, which still emits 10mG, the 50Hz will show 20mG while the Flat will show the real 10mG.
    The more advanced meters I know of, all work with the Flat system, so I don’t see why the Trifield should be any different. For that reason, I recommend the Flat version of the Trifield. This way, you can compare the results with more advanced meters.
    We have both in stock, so you can decide which you prefer.
    We are centered in Israel and ship freely using registered air mail (to the UK as well).
    All the best,
    Yair Freilich

    Thanks,

    Steve.

  • Sue said,

    Hi Steve,

    I read about the difference between the 50Hz, 60Hz and Flat version Trifield meters at the Radmeter, and at first wanted the Flat version because it revealed the true mG value, regardless of the frequency.

    I called AlphaLab Inc, the company that manufactures the Trifield meter, to see what they had to say about these different versions. They agreed that the Flat version gives the accurate mG reading, but they usually recommend the 50Hz or 60Hz versions (depending on your country’s power frequency) because these versions reflect how the body responds to the magnetic fields when the frequency is increased. And that most people buy the meter to help them understand the effects EMF’s have on their body.

    So even though the Flat version will give the accurate measurement of 10mG at 100Hz while the 50Hz version will measure 20mG, it’s the 50Hz version that lets you know that your body is reacting as though the mG has doubled. I bought the 60hz 100XE model because that is what I am interested in. Figured if for some reason I am interested in the true mG reading and know the frequency has doubled, I can divide by meter reading by 2.

    Sue

  • Lloyd said,

    Hi Steve
    Sue explains this well….whats important is understanding the potential dangers and effects of EMFs rather than the absolute readings….in any case, no meter in this price range is capable of giving you a “true” reading….my preference is for the standard weighted version as sold by Amazon.
    To answer your other question – yes’ I do live a normal life now. I lay out the details on this in the opening pages of my book. Good luck with your recovery.

  • Mike Lavenco said,

    Hi Lloyd,
    I just purchased the Triefield 100xe. It seems to work great, and I was shocked to see the level of EMFs in my car. I went to test the level of EMFs from a 500Kv transmission line near a house I was thinking of purchasing. When I was directly under the line, I was getting a reading of 1.0-1.5 Millagauss. Does that seem right? I thought it would be much higher. I went to a few other transmission lines, and the highest reading I got was 4.0 Millagauss. I thought the readings would be much higher especially under the lines. These ower lines were all located in Middlesex County New Jersey. What are your thoughts. Thanks, Mike.

  • Lloyd said,

    Hi Mark
    Your readings sound plausible. You need to take measurements at different times of the day….the magnetic fields are proportional to the current flow….early evening when people are cooking and watching TV you would expect it to be higher.

  • Alex said,

    Hello Lloyd,

    I live in the apartment with surrounding 24/7 neighbor wifi and two cell phone towers, in which they are around 50 and 100 meters away.

    I found the android applications in smartphone that can measure the strength of wifi. I use it to measure the wifi strength of my neighbors; the highest reading is -50 dbm and several readings with around -60 dBm or less. I recently purchased the Tenmars TM-194, EMF Magnetic Field Meter (Display resolution 0.001mW/cm^2) to measure the radiation strength of the two cell phone; I can get close to the two towers to nearest around 25 meters but the emf reading is still zero. I would like to ask you that is the emf level in my apartment safe to live with?

    Thanks

  • Lloyd said,

    Hi Alex
    Whats a safe level of EMF exposure? Its a difficult question to answer because it depends on so many factors…the best source I can cite is the BioInitiative Report…..the 2012 report recommends a precautionary level of 0.0003 μW/cm2 to 0.0006 μW/cm2 see http://www.electricsense.com/4766/bioinitiative-report-2012-emf-dangers-health/
    I have never tested the Tenmars meter but it looks like a microwave oven leakage detector. To get reliable readings you need a proper RF meter…

  • bob said,

    I’m confused since you said the Trifield XE 100 meter can be used to test Smart meters, but later said the Trifield XE 100 is NOT very accurate to test smart meters. I like the 3 Axis feature and your video on the Trifield XE, however, I want to hear your final answer on buying it to test the Smart Meter and its RF frequencies into my house!
    The Cornet is a lot more money!

  • Lloyd said,

    I don’t recommend the Trifield 100XE for measuring smart meter radiation. If you’re looking for a reliable RF meter in the same price band I recommend the Cornet ED75, see http://www.electricsense.com/3649/cornet-ed75-emf-meter-my-review/ or if your budget can stretch to it the Acoustimeter AM-10 RF Meter.

  • Gawain said,

    Hi Lloyd. Many thanks for the information you’ve made available on this site. It’s really opened my eyes to the dangers of EMFs. I’ve been testing my home and working environment with the Trifield 100XE, and am shocked how much magnetic field I’m exposed to sitting at my desk at work all day. I was struggling to locate the source (there’s a lot of electrical items around me, but they aren’t that powerful) until I realised that it’s the mass of heavy duty electrical cabling feeding the factory next door to our office! The needle goes off the scale right where I sit. I’m assuming that the best thing to do would be to move desks, but that’s easier said than done due to lack of space options! Is there anything I could request to be done to shield the area around me, but that may be futile, as it seems that it’s also emanating from the floor as well? Thanks, Gawain.

  • Lloyd said,

    Hi Gawain
    Magnetic field shielding is possible using a roll of Giron (see lessemf) ….its not cheap but it is effective….measure with your Trifield before and after OR if you can, move your desk.

  • Anthony said,

    Hi Lloyd
    I am currently using a laptop as a stationary at home, and have turned off everything function I don’t need like wifi and bluetooth. I have also turned the screen brightness to the lowest settings which helps a lot, together with tilting the computer up on the back so I avoid the radiation from the backside which is usually high. Still I have some minor symptoms I want to stop, so either Im going to a stationary or special laptop/tablet.

    Do you know why no manufacturer makes a laptop with low emf, it should be a market for it. As I have tried to use external 24″ display with my laptop but I don´t feel it makes it much better as the large display seems to emit large amounts of emf, even at range. What specific displays have you found emits low emf?

  • Lloyd said,

    Hi Anthony
    “Do you know why no manufacturer makes a laptop with low emf”— probably because no manufacturer has cottoned on to the fact that there is a market for a low EMF computer….it wouldn’t be difficult to produce one….. and possibly also that to produce one would bring recognition of the fact that people do experience health problems with low level non-ionizing radiation from these devices. I haven’t tried them but I know lowemfoffice.com do monitor shielding to create low EMF monitors.

  • Louay said,

    Hi

    This is a great site with so much information. Also it helps that you seem to reply to posters’ questions. I read some reviews for the trifield meter on the US Amazon site and there were many 1 star reviews saying that this meter was a waste of money and that the readings it gives are very inaccurate.

    To be honest I find sometimes reviews can make things more confusing and complicated because there will always be naysayers and negative people, but some of the reviews really put me off this meter. What are your thoughts?

    Also I was wondering what your opinion is on those homeplug systems that allow you to create a wired computer network through the house’s electrical outlets/plugs? This is the product I am talking about on Amazon: http://snipurl.com/27kzfch

    Thanks

  • Lloyd said,

    Hi
    Powerline adapters might sound like a good idea but they stream radio frequency signals (RF radiation) into the wiring throughout your home. The problem is that what goes into your wiring doesnt stay in your wiring it permeates out into your rooms and into whoever is in those rooms (you). I know lots of electrically sensitive people that have issues with this technology…a hardwired internet connection is safer.

  • Guy said,

    Hi Lloyd,
    Great site, I have a quick question. My wife suggests we buy the FW Bell 4180 (or Bell 4190) EMF gaussmeter because they sell it in Sydney and it’s good reviews. Have you reviewed this EMF reader? If so how does it compare to the Trifield 100XE EMF Meter?
    Thanks for you site and comments.

  • Lloyd said,

    Hi Guy
    I’ve not tested the Bell meters, but these meters only measure magnetic fields. The Trifield also measures electric fields and RF radiation…Radmeters delivers the Trifield to Australia.

    Dear Lloyd.
    I am a Researcher in the field of Geopathic stress. I am just trying to buy a good EMF meter, which can pick up the EMF generated by the Geo Stress Lines, which as you might know, are the stressed water lines underneath Earth, that can emit strong EMRs , which can reach upto 6000metres above earth’s surface. I am looking for a meter which can detect this EMF. Suppose I cut off all the power to a house, which has Geo Stress and then take this meter near to Geo lines found, it should show the EMR/EMF . Can TriField 100XE help me in this? BTW I live in Bangalore, India.

  • Disappointed said,

    There are better devices on the market such as the FW Bell 4180. Check each devices specs and you will find the FW Bell series are considered accurate whereas the Trifield is scientifically regarded as inaccurate. Check for yourself

  • Lloyd said,

    The Bell costs well over twice the price of the Trifield and many people just can’t afford $300 to buy an EMF meter. And even if you’ve got the money to buy the Bell the Trifield still has a lot to offer…it measures electrical and radio frequency radiation…the Bell only measures magnetic fields.

  • Louay said,

    Hi Lloyd. Regarding your answer to my question above on the powerline adapters. I would really like to turn off the wi-fi on my router but live in a big house with many people who access the wi-fi. It is not feasible at the moment to have wired network cables to all the different rooms upstairs. With this is mind how bad would you say the powerline adapters are? Are its harms just as bad as wi-fi or would you say by using the adapters and turning off the wi-fi the benefits would outweigh any harms? I would really appreciate your thoughts on this. Sorry for perhaps taking the discussion off topic to the article but it’s just relating to my previous comment. Thanks.

  • Lloyd Burrell said,

    I’d like to reassure you and say that in terms of EMF exposures powerline adapters are safer than Wifi, if I did it would be all guesswork…I know of no studies on this subject.

  • Jason said,

    Hi Lloyd, I am interested in being able to test for all electro smog however my primary concern at the moment is a nearby cell phone tower. Would this meter test for those antenna? Or, would it be better to go for the Cornet ED78S or Acousticom 2? Of course it would be better to buy one meter to test for all three frequencies, but only if the RF reading part would be sufficient. Any advice would be greatly appreciated. Which one tests microwave ovens? Thanks, Jason

  • Lloyd Burrell said,

    Hi Jason
    The Cornet ED78S or Acousticom 2 are a good choice for measuring cell tower radiation….the Trifield is not suitable for this. Microwave ovens emit RF radiation and magnetic fields in which case the ED78S, which measures both these, might be the better choice for you.

  • Steve said,

    Hi Lloyd!
    I just bought your E-book and read it in one day (some sections twice). I’ve been EMF sensitive for 12 years when my cell phone seemed to break through my head… but recently, because of tons of stress, my whole body has broken down… chronic fatigue, massive weight loss, muscle weakness… the whole 9 yards.
    I’m sensitive to EVERYTHING electrical now. I can function… but sometimes barely.
    If I want to measure EMF mostly in my home and office (including stereo systems and speakers, cell phones, computer monitors and hard-drives, far infra red home sauna, phones, appliances, etc.)… is the best device for me the Trifield 100XE?
    Also, I turned the electricity in my bedroom off at the fusebox last night, and still got symptoms. I do have a newer mattress (hypoallergenic) that has wrapped coil technology. Am I possibly getting symptoms from sleeping on this?
    Thanks… I’m sure I’ll be writing more, as I’m new to this.
    I would like a professional to come out and modify my faulty jacks, do some grounding work, etc. Do I just hire a regular electrician for this?
    steve
    I’m sure

  • Lloyd Burrell said,

    Hi Steve
    “Is the best device for me the Trifield 100XE?” — no one meter can measure everything you are trying to measure here. You would need the Trifield and a sensitive RF meter (Acousticom 2 is a good choice) to measure everything you mention – read carefully my reviews so you can see what each meter does for the price.
    “Also, I turned the electricity in my bedroom off at the fusebox last night, and still got symptoms. I do have a newer mattress (hypoallergenic) that has wrapped coil technology. Am I possibly getting symptoms from sleeping on this?” — Your body doesn’t react instantaneously to changes you make in your environment, turn off the power for two or three weeks and then see how you feel & if possible turn off the power in the room immediately above or below your bedroom.
    “I would like a professional to come out and modify my faulty jacks, do some grounding work, etc. Do I just hire a regular electrician for this?” — Most electricians know little about EMF exposures…it’s not in their training. You might be lucky in finding one with knowledge on this (ask them over the phone) at worst find an electrician with a sympathetic ear with whom you can work solutions out with.

  • Rhonda said,

    Just purchased the Trifield meter and had my eyes opened! I have been working in a constant 10-25 mG magnetic field from my calculator and a basestation radio for nearly 5 years!!! I have moved both these items far enough away to put my work area back in the “safe” zone, but I can’t get rid of them completely. Any ideas on shielding them so I can have them within reach but not get constantly bombarded with the magnetic field? The electric field is fine as is the RF field. But that magnetic field score stays high and goes off the scale the minute I get very close. So much for touching the calculator!!!

  • Lloyd Burrell said,

    Magnetic fields are the hardest to shield….it is possible, all depends what lengths you are willing to go to. This company http://www.aitsafe.com/go.htm?go=www.lessemf.com/mag-shld.html&afid=49151&tm=90&im=1#273 sells a product called Giron which is very effective for magnetic field shielding.

  • Pat said,

    Hi Lloyd,
    A few weeks ago I had written to you regarding my daughters’ dorm room and her sleeping right next to the ethernet cable box (which both girls’ laptops are plugged into). I appreciated your response. The school has suggested they could possibly move the box so we are waiting to hear if that happens. You suggested testing with a meter and I was wondering which meter you would recommend. I would also use it to test around my own home. Does the Trifield 100XE or the Cornet ED78S make sense? I’ve read your reviews but not sure which one would work best in our situation. I need it to be fairly easy to use and not too expensive.
    Thanks, Pat

  • Lloyd Burrell said,

    Hi Pat
    In my last comment I said “you would want readings on RF radiation(possible leakage from the cables) electrical fields and possibly magnetic fields” unfortunately there’s no one meter that can give you all this information. Assuming your budget is limited I would go for the Cornet ED78S (measures RF and MF), if your budget will stand it you should also purchase the ME3030B (for electric fields).

  • Andy said,

    Hi Lloyd,
    I can get the model extech radio frequency emf strength meter model 480836.
    Would you say this is a better option for the money than the trifield 100xe.
    Thankyou

  • Lloyd Burrell said,

    Hi Andy
    I’ve not tested the Extech meter so I can’t really comment….but just going on the technical description, the Extech is an RF meter…..and it only measures RF radiation and its limited to 3.5Ghz….. the Trifield is an all round meter but not best suited to RF measurements…if you want to measure RF sources I recommend the Cornet ED78S or Acousticom 2.

  • Maikki said,

    Hi! IS radmeters a safe place to order from? I am from Europe and i want to buy this meter. I cant find any reviews on radmeters. Where is it located?

  • Lloyd Burrell said,

    I’ve bought several meters for myself through Radmeters and lots of my readers have purchased from them on my recommendation, they’re a reputable company – they’re based in Israel.

  • Maikki said,

    Hi! Sorry, i would like more info on the Trifield flat model. I dont understand why the 50hz would be more accurate. Thanks

  • Lloyd Burrell said,

    The difference is in gaussmeter mode…the flat response meter is best designed for scientific measurement where you are looking for a ‘true’ reading….if you’re taking readings for health reasons, better to buy a weighted response meter which reflects the amount of current induced onto the body….which underlies the biological effects….which is the reason these readings are of interest.

  • Brenda said,

    Hi Lloyd, in an earlier reply to someone you said that the Trifield 100XE has a frequency of 40 Hz to 500 Hz, but on the manufacturers website, their specs say 40 Hz – 100 KHz. I’m confused as to the discrepancy.

    Also, I have a question about dirty electricity… do regular EMF meters measure dirty electricity (seems like they would since some of them do go up into the higher frequency range which is where dirty electricity exists)? If yes, couldn’t that give you a potentially false reading when you’re trying to find out the magnetic field or electric field of something? Would it be better to purchase a meter that doesn’t go up to such high frequencies? If yes, what would you recommend as the highest frequency?

  • Lloyd Burrell said,

    The Trifield 100XE measures in the frequency range 40 Hz to 100 KHz BUT the weighted reading only operates in the range 40 Hz to 500 Hz (the concept of weighted reading stops at 500 Hz)….weighted reading means you are getting a reading modified to reflect the impact on the body rather than a ‘true’ reading (which is less relevant)….it means, for instance, at 120 Hz you get twice the reading (Mg & V/m) as at 60 Hz. I wouldn’t be overly concerned with all this…it complicates things unnecessarily.
    Some higher end EMF meters can measure dirty electricity – I recommend a Microsurge meter for this, which requires no technical understanding.

  • Lynn D said,

    WHich meter would be good to measure earth electicity? have seen mention of it in various you tube and articles and also when then tech came from electric company to measure EMF, she said sometimes the earths electricity can “bulge and interupt the power in a house.. Hope this question makes sense. Thank you

  • Lloyd Burrell said,

    The earth’s surface is covered by geo-electromagnetic field lines – Hartmann lines and the Curry Net – which forms an invisible grid over the earth’s surface. Where these lines cross, knots are formed which give rise to elevated levels of radiation (geopathic stress) which can lead to ill health but these forces are much too subtle to “interrupt the power in a house” and too subtle to be measured by an EMF meter….dowsers are capable of detecting these energies.

  • Wim (Netherlands) said,

    Hi Lloyd,

    First of all, I would like to thank you for your informative, eye-opening website which I came across and your willingness to share your knowledge and experience and help people.

    As a result, I read comments on the Trifield 100XE meter at Amazon, but found a few disturbing one star ratings, in which people claim that the Trifield readings are way off (much higher) from readings done with professional equipment.

    As you wrote earlier, one cannot expect correct readings for this price. However, if results are far off the truth, than it may lead to unnecessary fear e.g..

    As I understand, you have multiple meters, so you will probably have cross tested readings and compared them.
    My question is if those one-star-rating-people are right or not. Are the readings a bit or way off the truth?

    Thank you in advance and I do apologize for mistakes in English (it’s not my primary language).

  • Lloyd Burrell said,

    There are always people who will criticize Wim….there are better EMF meters on the market but they cost a lot more money…I’ve always concentrated on reviewing meters which seemed to offer good value for money and this is the case with the Trifield 100XE. Before you buy this EMF meter you need to ask yourself what EMFs you want to test and how much you can afford to pay….the ideal combination to start with is the Trifield (or 3030B) with a good RF meter…if you can only afford one meter the Trifield is a good starter meter.

  • Wim (Netherlands) said,

    Thank you for your answer and a happy new year!

  • mark said,

    Hi Lloyd,

    What meter would you recommend to measure cell phone radiation?

  • Lloyd Burrell said,

    Mark,
    You need a fairly sensitive RF meter….the Acoustimeter, Acousticom 2, or Cornet meters (slightly cheaper) are suitable – see my reviews.

  • Mirko said,

    Hello Lloyd, thanks for the useful info you’ve been providing us for quite some time now.

    I just received Trifield 100XE from the States, and I ordered it for the use of basic EMF/ELF detection around my apartment.

    Now, can you please advise me how should I set my Trifield (probably ”Electric”) in order to detect fields caused by wiring (in the building) inside floors and walls..?

    The only reason I bought the device is because I think my apartment has a lot of bad, old and not properly secured wiring.

    Thanks in advance and best regards from Belgrade, Serbia.

    All the best in New Year.

    Mirko

  • Lloyd Burrell said,

    Turn the dial to the ‘Electric’ setting, watch the top scale (multiply by 10 to get a reading in volts/meter – so if the needle points to 10 that means 100 V/m), take measurements in each room passing your meter slowly along walls and floors.

  • Mirko said,

    Thanks Lloyd, I’m interested to hear your opinion on one more thing. What can be the cause of very high readings (from floor and about one meter high) of Magnetic fields in one of my rooms..? Again, thanks and best regards.

  • Lloyd Burrell said,

    Assuming there’s not the consumer electrical box nearby or substation or other major potential source of EMFs that sounds very much like wiring errors….anything over a few mG is a cause for concern….I strongly advise you to get a licensed electrician in ASAP to check your wiring. I’d be interested to know how you get on.

  • Mirko said,

    Sometimes the readings are skyrocketing to highest values in that room, sometimes they just drop all of a sudden, but at a certain line on the floor there’s a constant reading of about 4 mG and above, that’s why I think there’s a high voltage cable or very badly insulated or even wiring error. I am very determined to detect all of the harmful fields in the apartment. If I detect high readings on too many places, I’m ready to sell it and buy another one in different building. But if I have to choose another one, I’m pretty sure I’ll scan it with Trifield first. Hope I’ll be back with some answers soon.

  • Brian said,

    Hi Lloyd,

    Recently, my wife and had an accepted offer on a house. After our engineer was finished inspecting the house, I noticed that there were trees blocking the view of some high voltage meters in my backyard. They are approximately 250 meters away. I quickly ordered the trified meter that you recommended. We will receive it tomorrow. I am very concerned about the health risks of living near high voltage towers, especially with my 7 month old daughter. I will take readings tomorrow at different times during the day, but what ranges should I worry about? I understand that 3mg is in the bad range, but I dont like the idea of even being exposed to 1mg 24 hours a day 7 days a week. What is an average exposure reading? (Outside and inside) And, is the distance from my possible new house sufficient enough per say? I see websites that debate about safe zones/distances. Please help because contracts should be signed in two days. Your expert advice will be much appreciated.

    Thank you in advance,
    Brian

  • Brian said,

    P.S. the output on the high voltage towers are about 130 kilovolts.

  • Lloyd Burrell said,

    Neither me nor anyone else can say what constitutes a ‘safe’ level of exposure….the best guidance we have currently is from the BioInitiative Report which recommends a limit of 1 mG for magnetic fields.

  • Ed Roth said,

    I don’t mean to sound paranoid but I have two questions:
    1. does the Trifield detect wireless hidden cameras?
    2. if someone were eavesdropping on me with microwaves, would the Trifield detect it or would I need a device with a broader range like the Cornet ED85EX?

  • Lloyd Burrell said,

    Assuming the hidden cameras are wireless the ideal choice would be the ED85EX equipped with the near field antenna.

  • Jorge said,

    Hi Lloyd,

    Thank you for this website that helps many people like me who are in need for answers and explanations.

    I am looking for help because I do not feel sure in understanding this picture:

    We live in a townhouse that has a backyard. Right beside our fence there is an Electrical Substation.
    I borrowed an EMF reader (F.W.Bell Model 4180) which I set with axis X Y Z

    When I’m on my backyard I have three different readings:

    – Close to the fence: 6.7 micro Gauss
    – Middle of the backyard (halfway beteween the house and the fence): 3.5 micro Gauss
    – When I’m on the external wall of the house: 3.0 micro Gauss

    Same wall but from inside the house: 2.3 micro Gauss

    I will appreciate your expert opinion about these readings.

    Jorge

  • Patric Steele said,

    Thanks for all your great work Lloyd.Have high levels of heavy metals due to constant work exposure was looking at clearlight and sunlighten far infrared saunas for heavy metal detox because they show low emf test results both were just under 2mg?/ ug? which is below the max. safe U.S.A. standard of 3 mg/ug? but i noticed they had a picture of a Trifield meter in your review for both companies emf test.I believe far infrared waves are in the same rf class as microwaves although microwaves are the shortest and infrared are the longest should i get cornet e85 ex meter to get a more accurate reading when I check these saunas out in person.? Please correct me if I am wrong. Much Thanks, Patric

  • Lloyd Burrell said,

    Infra red saunas are a very effective way to detox…as far as possible you should always test as fully as possible any electrical devices you buy for EMF exposures (RF radiation, electric fields, magnetic fields and dirty electricity). The ED85EX will give you a reading for RF radiation only….unless you already have a magnetic field meter the Cornet ED78S might be a better choice for you….it allows you to measure magnetic fields and RF radiation.

  • jan said,

    hello

    I would like to measure high or medium voltage (I am not sure) from cables above a house. I was planning to a gigahertz ME3951A second hand for 3oo euros, which seemedlike a very good deal, and then I discovered this trifield. Do you think it could do the job for me as well? I am am doubt.

    This indicates the standards of EU I suppose, but how can I compare them to the advice of the bioinitiative report? The gighertz measures in nanotesla I believe, and the trifield shows milligaus, right?

    Many thanks!!

  • Giselle said,

    Hi Lloyd
    I would like to purchase the Trifield (for the home)and Cornet (cell phone), to show teenager how dangerous they are. Unfortunately Amazon and all other sites I have tried will not ship to Australia?

  • Lloyd Burrell said,

    Radmeters ship worldwide and they offer good service see, http://www.radmeters.com/Trifield-100XE-fr.html and for cell phone radiation the ED85EX with the near field probe antenna http://www.radmeters.com/Cornet-ED85EX-fr.html

  • Albert said,

    Hi Lloyd,
    I actually bought a Trifield meter , but I’m confused with the measures it gave me, in specifications says “calibrated to 60 hz, so if it measure 3mG at 60hz source, … but it’ll measure 6mG at 120hz source” , and I wonder when I measure 10mG and I know the source is a transmitter at 480Hz, the real measure is 1.25 mG ? Am I wrong ?

  • Lloyd Burrell said,

    I can see your logic but I’m not sure if this calculation would give you an accurate reading…especially if you’re using the weighted frequency meter.

  • Ace said,

    I think I finally have to take the plunge and buy a Trifield Meter, for my RF sensitivity,

    …but have some serious questions:

    1. Will the meter just measure activity of things it is extremely close to, or could it detect a cell phone that is in the house but a larger distance away?

    2. Could it detect RF that is coming in from outside agencies such as a neighbor using wi-fi or a smart meter outside the house?

    3. Does it only detect a cell phone when it is receiving or making a call, or can it detect a cell phone that is simply powered on?

    4. Have you ever seen a Trifield Meter give a positive reading even when a cell phone was powered off?

    My main concern is I will spend up to $200 on a meter, and it won’t really tell me much useful information. I get sick from a lot of RF including cell phones that are further away and sometimes even off (yes, it is true).

    Would appreciate advice.

  • Lloyd Burrell said,

    If you want to measure RF radiation the Trifield 100XE is not the best choice by any means….see the links in my article above to the Acoustimeter and Cornet meters.

  • Lattishia said,

    Hi Lloyd! I love all the information you’ve provided, thank you. I purchased a TriField Meter and used it around the house today. I’m hoping you can answer my question as if I’m 10 so I don’t misunderstand. lol Where I sit at my desk all day, there is barely a reading at all. A foot and 1/2 away near the router, modem, printer, etc. there is a pretty high reading. Does this mean that as long as there is almost no reading on my meter where I actually sit, that I’m sitting in a safe zone? :) Thanks so much!

  • Lloyd Burrell said,

    Its not quite that simple….the Trifield measures different forms of EMFs…..it depends what you’re measuring and what scale you’re using….I suggest you have a good read of the instruction book that came with your meter to understand this better.

  • Pat said,

    Hi Lloyd,
    Thanks for all your great work. I am not sure if I am EMF sensitive. I have a lot of pain in my hips, shoulders, buttocks and neck at times. I not sure if EMF is the cause or not. It probably does have something to do with my pain. Anyways I was just wondering, out of the meters/detectors you review, what would be the best 2 you would recommend to most accurately find the most sources of EMF. Also if you included the ME3830B, what would be your 2 recommended meters/detectors. Thanks so much!

  • Lloyd Burrell said,

    The ultimate combo in consumer grade EMF meters is the ME3030B coupled with the Acoustimeter….these 2 meters will give you reasonably reliable readings for RF radiation, electric fields & magnetic fields.

  • Pat said,

    Hi Lloyd, Recently numerous Extra High Voltage Power lines, Cell Towers and Antennas have been constructed near my home anywhere from .55 to 4.00 miles. Some reach a height of 266′ tall and extremely wide. I truly believe these are causing my symptoms of ears ringing, and other increasing night time/early morning symptoms.

    I am considering purchasing the Trifield 100XE meter you recommend for assessing the magnetic fields coming into my home.

    Is this meter appropriate or would a Gauss meter be a better fit for measuring this exposure?

    I unplug nearly everything in my home at night – except freezer, refrigerator and digital clock on gas stove. The microwave oven was discarded years ago; the cell phone was shut off and I use only a land line phone.
    I use very little electricity and do not have a smart meter but same analog meter and pay small opt-out “fee” (extortion!!). However, the next door neighbor has a smart meter facing my home about 45 feet away. Thank you for your advice. Pat

  • Lloyd Burrell said,

    The Trifield 100XE has a Gauss meter function (i.e. it measures magnetic fields)….for the money its a good meter but its very unlikely that at 0.55 miles you would pick up a reading of magnetic fields from the power lines with this or any other gaussmeter for that matter…too far. In your circumstances a better choice might be the Cornet ED78S which will allow you to measure magnetic fields and also the RF radiation from nearby smart meters and cell towers.

  • paddy said,

    Hi Lloyd – thanks for a great site and all the incredible information you’ve shared.

    You mentioned that people living outside of the US need a 50Hz version of the Trifield meter. Even on the RadMeters site, i can’t seem to see any differentiation of models for US and/or Europe.

    Is this still relevant or have they made one product that works properly regardless of where you live?

  • Lloyd Burrell said,

    There are different versions of the Trifield 100XE meter available. Radmeters sell both the Flat version and the 50Hz Weighted value version….unless you specify otherwise they send out the Flat version…..which works anywhere….my preference is for the weighted value version for the reasons laid out in my comments above.

  • paddy said,

    Thanks for the response Lloyd. As you’ve highlighted, the weighted value version is more suitable.

    You mentioned – “unless you specify otherwise they send out the Flat version…..which works anywhere…. – does this mean that the weighted version only works in the US, or is limited to certain countries where it will work properly?

  • Lloyd Burrell said,

    The 60 Hz weighted version is designed to work in the US and the 50 Hz version in certain other countries – see the link above for a country listing.

  • Jade said,

    I am very sensitive to RF, I have to be in an environment where my Acoustimeter AM-10 is not registering anything visual or auditory. I have a Cornet ED85EX and just used the whip antenna supplied, I have found this meter to be not sensitive enough for my ES. To give an example, my home has the neighbours BT Wi-Fi (you can tell the supplier by the sound), their DECT phones, mobile phones and 3G & 4G mobile transmitters, I have shielded a few rooms, so I can still use them, my Acoustimeter is silent here, I take it into radiation and it lights up green and orange and lets me hear the awful beating of Wi-Fi and screaming of the mobile transmitters, I am feeling ill, but the Cornet is not registering anything at all, totally flat-lining, I have to put it into an area registering at least in the high green to orange of my Acoustimeter for it to even get a low signal, in full (home) Wi-Fi or under a mast it peaks. There is also no way to tell what is causing the readings, I I no longer use it now I have the Acoustimeter, I carry it around with me, even shopping to monitor the changing environment. I felt a burning last year in my forehead in Sainsbury’s which I get from Wi-Fi (even from a weak signal) I switched on my meter to hear the Wi-Fi sound, which I had previously not heard on my meter in there, the manager knew noting about having anything new switched on and told me he doesn’t agree with Wi-Fi and doesn’t have it at home. I heard it in Wilkinson’s (they denied having it, even though they just had white boxes near the ceiling installed at the time)and Morrison’s, I cannot go into these shops anymore, M&S is so high that even my cornet meter was challenged! Walking by Barclay’s and Santander I pick up WiFi too.

    To increase the Acoustimeters sensitivity so I can shield even better I attach it to headphones or some speakers for a PC, be careful with the headphones as the noises can be deafening when they are hardly noticeable without amplification, especially if a neighbour is making a mobile call and connecting. I have just purchased a Multimeter by Extech the EX330 model recommended on some grounding websites, it is very sensitive for checking that earthing is working and for checking AC voltages around the home, I have recently grounded a lamp which made me tired when switched on and now it doesn’t. It also detects and gives readings of voltages as it has a none-contact voltage detector built into it. I have the CellSensor too for magnetic fields, this is very good and has two sensitivity levels. With all three of these devices I feel able to measure all that the Trifield measures and the only meter I think that we need to always carry about with us is the RF meter, the Acoustimeter comes in a hard plastic case so it is perfect for this. A portable radio tuned to AM is also a quick and cheap way to detect interference resonance given off from equipment I am going to buy a Stetzer meter next to measure dirty electricity. I can hear other frequencies in the environment though my my ears (Tinnitus) but I don’t think they are made by civilians (I cannot shield these) I think they are due to Geo-Engineering/weather modification and HAARP.

  • Fee said,

    Hi I have just purchased the trifield as I seemed to get relatively high electric fields from a meter I had hired on checking my walls and floors for internal wiring. After paying an electrician for 7hours he has issued an electrical insulation certificate saying the wiring is fine but I still got readings of 30-40 v/m 30cms away from walls and floors 60v/m at 50cm away from a light socket. I saw one Australian company saying that the trifield is not good at measuring electric fields from wiring. is this true? surely it picks up electric fields wherever they exist? I had understood that the RF and magnetic fields were the worst fields and have been able to find little info on what levels become dangerous- could you let me know? Also if the trifield is 3 axial it may come out with even higher readings than the meter I hired?
    Many thanks. Fee

  • Lloyd Burrell said,

    Fee,
    The Trifield is a good meter for the price but because it isn’t equipped with a ground lead there is potential for a fairly high margin of error on the electric field settings….so it measures the electric fields but the readings can be quite inaccurate….if you are wanting more accurate readings the ME3030B is a better choice….but it doesn’t measure RF radiation. It’s impossible to say with certainty which are the ‘worst’ fields….for a better understanding of whats ‘safe’ see the BioInitiative Report 2012

  • Linda said,

    Hi Lloyd

    I’m confused, I know that high magnetic reading are dangerous, are high ‘electrical readings’ also dangerous?

    We have an offer on a house, however the house we are interested in is located very close to power / utility lines. I was told the powerlines were ‘low level’ power lines. When I hold the tri-field meter under the power lines while turned to the ‘electrical reading’ it goes off the scale the higher I hold the meter. However the magnetic reading is very minimal. Should I be concerned that the electrical reading is high. It also reads very high electric when I take a reading from the porch of the new house.
    Thanks for all your help.

  • Lloyd Burrell said,

    Hi Linda
    High electrical fields are also considered dangerous but there is much less research on this subject…..Roger Coghill has done important research on this. Whats important are the readings in your home…..both electric and magnetic fields fall off with distance…..you need to determine if the electric fields on your porch are emanating from the powerlines or from sources inside your home.

    Hi Lloyd
    The high electrical reading are emanating from the power lines, as the home is in the process of being built and the electrical has not been wired. Unfortunately the very high electrical readings are from the back porch and yard. However the magnetic readings are minimal. Once inside the house the electrical does drop off considerably.

    Thank you for all your valuable information.
    Linda

    hi, if i want to test my voltage before and after on my body using a grounding sheet, would this work?

  • Lloyd Burrell said,

    Hi Coleen,
    You need a body voltage meter to test for this or a simple Multimeter, see my amazon store http://www.electricsense.com/emf-protection-store/ (my Amazon store page also has instructions for testing body voltage).

    Lloyd, the modified “Broadband” version of this meter adds sensitivity to not only the RF, but also the EM. It states that is goes down do 5Hz for EM instead of 50Hz, the upper range is still 100Hz.

    It costs about 40 bucks more for the extended range. Is there any real world benefit to having the additional range for EM from 5Hz to 50Hz (which the std 100xe lacks)?

  • Lloyd Burrell said,

    Hi Jay,

    Being able to measure EMFs at powerfrequency levels (what’s found in your home or office) is what most people are interested in, which is why I recommend the standard weighted version of the Trifield 100XE (my Amazon link if you are in the US)…..if you’re measuring EMFs for health reasons it gives the most relevant information – if you’re not clear what the weighted version does see my explanation above. The additional functionality/sensitivity of the Broadband version of the Trifield is of little practical benefit for most users.

    I have a friend who has been recently diagnosed with cancer. They have lived in the same home for 40 years, which is approximately 100 feet from one of those electrical high wires (18 cables). What meter would you recommend that I buy so they can measure the electromagnetic field in their home? I really appreciate your help.

  • Lloyd Burrell said,

    For your friends you need to measure magnetic and electric fields…..the Trifield meter can do this for you.

    Hi Lloyd,
    I just received this meter. We are looking to rent a house next to power lines and want to find out what the emf levels are inside the house. Will this meter pick up emf levels from the power lines inside the home or do we need a different meter for that?
    Thank you!

  • Nicole said,

    Thank you Lloyd! Thanks to this meter, we found that outside the house we were looking to rent is a level 10 and inside is a level 9. We will continue to look and take this meter to every house we look at.

    Hi Lloyd,
    We found a house that barely registered on the trifield meter inside and out when we first looked at it. I did overlook one thing and I can’t believe I did. We do not have possession of the house yet but drove by it yesterday. I noticed the power lines to the house run into the master bedroom. It is too late to get our deposit back so I am wondering since the meter still barely registered in the bedroom, are we safe from the emf’s or does it depend on the time of day? Ironically, we thought to check the wall that the bedroom shares with the a/c unit. Thank you for all that you do!

    Hi Lloyd- Would you recommend the Trifeld for measuring a new generation cell tower. I ma new this field an would something I could understand.
    Thanks– JOE

  • Lloyd Burrell said,

    Hi Joe
    A better choice for measuring cell tower radiation would be:
    Acoustimeter
    Acousticom 2
    Cornet ED85EX (more complicated)
