  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 cannot 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

  I have done some research on this, Wikipedia has a list of electricity supply frequencies by country. It is showing 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). I do not know of any Indian company selling the Trifield but this retailer ships to India.

  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.

• 

  Lloyd said,

  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.

• 

  Massimo said,

  Lloyd

  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.

  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.

  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!

  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.

  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

  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/

  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

  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.

  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.

  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.

  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.

  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.

  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.
