Cornet ED88T EMF Meter – My Review

cornet ed88t emf meterThe Cornet ED88T EMF meter is the most recent addition to the Cornet range.

If you’re new to the world of EMFs then it can be difficult to know what to look for. There is a tendency to look solely at price when comparing different meters.

Price is important. But what’s most important is understanding what you’re getting for your money. Because otherwise, no matter what the price, there's a real possibility you’re going to end up wasting your money on the wrong EMF meter.

What I’ve set out to do here is review this meter in a simple, no nonsense way, so that you can decide if the Cornet ED88T is the right EMF meter for you. But the first question I want to address is even more fundamental.

Do You Need An EMF Meter?

There are now thousands of independent studies which link electromagnetic field exposures from supposedly harmless devices, which we all use in our homes and work places, to a long list of serious diseases, including cancer, cardiovascular disease, diabetes, suicide, epilepsy, to name just a few.

The only way to understand what you're exposing yourself to is by using a device like the Cornet ED88T EMF meter. If you need more convincing just spend a few moments reading the articles and readers comments on this website – the reason I started this website was because I got very sick from these supposedly harmless EMF exposures.

Okay. Now let's get the technical part out of the way.

What Can You Measure with the Cornet ED88T EMF meter?

This EMF meter measures 3 types of EMFs. When you switch it on the first thing it measures is radio frequency radiation.

Radio Frequency Meter

Most RF radiation these days comes in the form of digital bursts. Whether it be GSM, TDMA, CDMA, WiFi, WiMax, ZigBee or UWB, the Cornet ED88T EMF meter can measure all these technologies.

In terms of devices, it can measure EMFs from devices such as:

  • Cell phones and smart phones
  • Smart meters and smart appliances in the home
  • Bluetooth devices
  • Cell phone towers (mobile base stations)
  • Microwave ovens
  • Wireless routers and modems
  • Cordless (DECT) phones
  • WiMax
  • Spy cameras
  • Digital baby monitors
  • Digital TV
  • A/V Sender Receivers
  • Wireless burglar alarms
  • Wireless video games (Playsation, Xbox and the like)

Magnetic And Electric Field Meter

The Cornet ED88T can also measure two other types of EMFs, low frequency AC magnetic fields and electric fields. It can measure EMFs from things like:

  • electrical devices in your home: electric hair dryer, clock radio, ovens, dishwasher etc
  • electrical powerlines
  • your house wiring
  • electrical substation EMFs

What Are The Most Important Features of The Cornet ED88T?

There are 3 important features I need to draw your attention to:

  • The single most important feature is it’s tri-mode function. Some meters measure only RF radiation. Others only measure magnetic fields, typically called gauss meters. This meter measures RF radiation, magnetic fields and electric fields. But more than that, it’s how it performs these functions.
  • What sets this EMF meter apart is that first and foremost it offers very good RF radiation functionality, that’s to say a broad frequency range with good sensitivity. The RF meter mode will be what interests most people that buy this meter. The frequency range is broad (100MHz – 8GHz) and by virtue of its improved sampling rate, 10,000 samples/sec, it offers very good sensitivity.
  • cornet ed88t frequency display functionThe third important feature is its frequency display function. That’s to say this meter goes beyond just telling you that there are RF exposures and the signal strength of those exposures. It also tells you the frequency of those exposures, in the range 100 Mhz to 2.7 Ghz.


Cornet ED88T Or Cornet ED78S?

The Cornet ED78S stands in good stead against the ED88T. You can read my review of the ED78S here. These 2 meters are very similar but ED88T offers the following additional features:

  • Electric field meter mode. The ED78S only measures RF radiation and magnetic fields.
  • Frequency display function. The ED78S only gives you signal strength information, it does not tell you the frequency of the signals you are measuring.
  • Ability to personalize the colored LED lights. The default setting for the LEDs on the other Cornet meters are the thermal exposure limits, which are misleading, to say the least. By going into the system setup menu (I explain in the video how to do this) you can change the settings so that green for instance corresponds with non-thermal levels as recommended by the the BioInitiative Report. Not every one will be interested in this feature but for regular users it is a definite plus.
  • The price. The Cornet ED88T is quite a bit more expensive. I believe the extra cost is will justified but if your budget is tight, the ED78S might be the better choice for you.

Cornet ED88T Or Cornet ED85EX?

The Cornet ED85EX is a dedicated RF meter. It only measures RF radiation. The advantage of the ED85EX is that you can add different antennas to give the meter improved performance, for instance to extend the frequency range or obtain more precise readings in the near field range.

Most people will be seduced by the tri-mode functionality of the ED88T. But if you already have a meter for measuring magnetic and electric fields and you are looking for the flexibility of being able to change antennas then the ED85EX may be a better choice for you.

You can read my review of the Cornet ED85EX here.

By way of a summary let’s look at the pros and cons.

The Pros

Why I like the Cornet ED88T EMF meter:

  1. Again, the biggest advantage of this meter is it’s tri-mode functionality, which means its like having 3 meters in one.
  2. It offers solid RF meter functionality. Its sensitivity. In RF mode it’s got this very good sample rate, a better sample rate than the ED78S and it also has good sensitivity for MF readings because it has two magnetic field settings.
  3. The sound function for RF mode. I’m a big fan of being able to hear the EMFs because it conveys so much information. While I was testing I noticed I was picking up RF radiation readings on the audio which was not shown on the display. Getting information on extremely low levels of EMFs is important. The more sensitive your EMF meter is, the better. Having this sound function definitely improves this aspect.
  4. The histogram function. Its the little box on the right of the LCD display. It shows the last 30 readings since you switched the meter on. This is ideal for measuring smart meter radiation which comes in short bursts. having the histogram and maximum signal level makes it easy to observe these bursts.
  5. Its price. At the moment to my knowledge there is no other EMF meter on the market which offers such broad functionality for such a low price.

The Cons

  1. I’m not a big fan of only having 3 buttons to explore all the functionalities of the meter. It is a sophisticated piece of kit, the user manual is not particularly user friendly so anyone buying this meter will have a learning curve to be able to use it properly. Which is one of the main reasons I did this video. What I suggest you do is with a permanent marker pen write an M next to the mode button and an H next to the hold button.
  2. The choice of measurement units. For magnetic field mode it gives you the main reading in Tesla. You have to look underneath at the small figures to get the milligauss reading (most of the international standards refer to mG). For RF mode the default setting is on mW/m2 (milliwatts per square meter). I prefer V/m (volts per meter) which you can select by going into the settings. To be fair there is alack of concensus on what measurement units are used, so this is a fairly minor point.

Cornet ED88TPlus

This section updated March 2019: the new version of the Cornet ED88T is the Cornet ED88TPlus. Is the new version any better? Yes, it has this additional functionality:

  1. an improved user interface (more buttons)
  2. a USB socket allows so you can connect it to your computer for data logging

These are all welcome improvements but essentially it's the same meter as the Cornet ED88T, it has the same sensitivity, the same frequency ranges and the same tri-mode function.

The new user interface is an improvement that all users will benefit from. The data logging function is good to have. Most people won't go to the trouble of connecting it to a PC but those that want to do that can.

Is It Suitable For Measuring 5G Radiation?

Update September 2019: 5G is the latest generation of cellular technology which is being introduced across the globe. Currently it's understood that the frequencies that will be used for 5G for the next few years will be sub 6 GHz—that's say below 6 GHz which falls within the frequency range of the Cornet ED88Tplus. So yes currently the Cornet ED88Tplus meter is suitable for measuring 5G.

Want to learn more about 5G? I have published an extensive article to address the question — is 5G dangerous?

  • damien said,

    must say, you do very honest and useful reviews of these meters.
    normally i’d do days of research before buying something like this, but this time I bought it after watching your video, as ive come to trust your word.

    excellent work well done and keep going with it. thanks

  • Erik Dalgaard said,

    Hello. Can ED88T measuring the digital radio signal (DAB) frequency from 180 to 240 MHz? you know the sound of the beep on the meter from DAB radio?

  • Lloyd Burrell said,

    @Damien – thanks for your kind comments.

    @Erik – where I live we don’t have DAB so I don’t know what sound these frequencies would generate on the Cornet’s audio…..but the ED88T can measure from 100 MHz right up to 8 Ghz so it’s perfectly suited to measuring DAB frequencies.

    Hi Lloyd,

    We need a meter but are traveling now and the guys have to make the final decision.

    We are trying to come up with an “action” plan. We have so many issues and now believe we are all impacted. We have a horrible city manager and now they are headed for smart electric meters, we already have a water smart poison one.
    This man is evil so we are trying to make a cover for it.
    So can this meter measure between the toes as the Geovital guy demonstrates?
    We have such an ill family member and have to start re mediation fixes soon.
    We will miss your sale as we can only buy one. It has to fit all of our needs.
    We depend on your expertise, skills and dedication Lloyd.
    Without you we would be lost.

  • Judy said,

    Hi Lloyd,
    Coming from a scrambled brain, I have no clue what I need to test. I have read several posts trying to figure it all out and I just get a headache with no further understanding. Could you do a post to help people like me with the basics of all of this? (Not just about this meter.)

  • PseudoGeek said,

    Under Technical Specifications, you said “bare with me and all will become clear.” Getting naked with you would be very weird. Hopefully you meant “bear with me…”

  • Lloyd Burrell said,

    @Calle – The Cornet ED88T cannot measure between your toes….as far as I know the meters you are talking about are specific to Geovital…they measure the radiation in the body. And come with a hefty price tag, over $1000. The ED88T measures the EMFs in your environment, as most EMF meters do. I suggest you watch the video above to get a good idea of what it does.

    @Judy – This topic can be daunting. I suggest you subscribe to me free report. This covers the fundamentals.

    @Pseudogeek – whoops! That’s funny. I’ve now corrected it.

  • Shirley Joy Jackson said,

    Lloyd, we will definitely be buying a Cornet ED88T, especially because of its expanded range (up to 8 GHz), but also its size, ease of carrying and convenience (particularly when traveling) and to augment our current equipment.

    I am sensitive and currently have a moderately high-end Gigahertz HF38B Analyser and its ‘companion’ ME 3030B Magnetic & Electric Analyser.

    I look forward to helping myself and others discern what’s happening – especially when I’ve felt particularly effected but unable to determine what was causing the irritation. For example – with lower frequencies, some much older cordless phones in the U.S. transmit on the lower end of the scale (below 800) and a friend of mine seemed to be very effected but I was unable to have him ‘see or hear’ what was happening.

    1. I’m used to looking at more sensitive microWatt readings. 1 microWatt = .001 milliWatt Does the Cornet 88T consistently use all four numerical places to the right of the decimal so that readings in the 1-to-99 microWatt range are consistently reported in those 3rd and 4th places to the right of the decimal? (Is the sample picture you provided above, that shows 0.0012, mean it is .0012 milliW or its equivalent, 12 microW? Please correct my math if I’m off.)

    2. In real time use, what happens when the source you are measuring has an abundance of transmissions OVER the top range of the 2.7 GHz spectrum indicator? Does the audio squeal more prominently? My sister has an antenna near her home that my Gigahertz only indicates an average of 20-30 microW/m2, but I feel much more is happening. IF much more is happening (an abundance of transmissions between 2.5 to 8GHz), how would the Cornet 88T respond? I want to be aware of these measures (or at least indicators), so that any shielding material is appropriately matched and/or tested on-site.

    For the price, it seems like even general feedback from this meter on either of these situations would be worth its weight in gold!

    Thank you for the time and care with which you explained this model of meter to us. And to those who are just starting to learn about these things…do subscribe to Lloyd’s free report, it will give you an easy but tremendous shift in your own self-confidence to navigate and make productive choices for yourself!

  • calle said,

    Thanks Lloyd and all who post.
    We are right south of a radio tower, and only two blocks from a huge multi unit cell tower. Have a smart water meter in the cellar and have a 117 year old house. Businesses surround us and now we all realize we are affected.
    To put it mildedly we are beyond worried.
    Memory problems, demineralizing teeth., absorption problems and the list goes on.
    Sleep disturbances for the guys and nothing helps. And our kitties “earth” in my plants all of the time. Dead plants as they totally smother them.
    Okay Lloyd will see if hubs will go to your site from his work computer and order this. Does it come with very good directions?
    As we only have 5000 jobs to do and I travel all of the time.
    The guys think I should learn it all and do it all.. I now have over 7 books on this subject.
    As I am going to open the eyes of my fellow health pros this Sept.
    Hope they don’t kill me…
    So can you extend the sale until next week?
    It is tax time and boy does that mean work over load.
    Thanks again Lloyd and if you ever come to America and hit the mid west the north Central or lower Midwest as in KCMO let us know.
    Or we can all camp in the wilderness and cook with solar. LOL

  • Daniel said,

    Hi Lloyd,

    This meter has two LF settings, LF600 and LF30. The LF600 is a higher frequency range than the LF30. These ranges contain electric and magnetic fields, but how do you tell whether the meter is picking up electric or magnetic fields?

    For example, my bedroom is next to the wall where the electricity comes into the building from the utility and splits into the meters for each flat (no smart meters fortunately!). I have measured fields higher than 1 mg extending into the room and so want to shield, but I don’t know whether to shield from just LF electric (cheap) or both magnetic and electric fields (expensive).

    Any advise would be appreciated.
