The Trifield TF2 EMF Meter – My Review

Posted by Lloyd Burrell on March 10, 2018 under EMF meters, Trifield meter | 23 Comments to Read

Trifield TF2 EMF MeterThe Trifield TF2 EMF meter is the most recent addition to the Trifield range.

EMFs can be confusing. I know when I’m buying something, if I don’t really fully understand what I’m buying then often I just go on price.

Price is important. But let’s not forget this is your health we’re talking about here. Just going for cheap can mean wasting your money on the wrong EMF meter and jeopardizing your health.

Below is my review of this meter in a simple, layman terms, so you can decide if the Trifield TF2 is the right EMF meter for you. But the first let’s start at the beginning.

Do You Really Need An EMF Meter?

Thousands of independent studies link electromagnetic field (EMF) exposures from supposedly harmless devices, which we all use in our homes and places of work, to a long list of serious diseases, including cancer, brain tumors, Alzheimer’s, cardiovascular disease, depression, diabetes, epilepsy, to name just a few.

The only way to know what you’re exposing yourself to is by using a device like the Trifield TF2.

Not convinced? Just spend a few moments looking at the articles and readers comments on this website – the reason why I started this website was because I got very sick from these supposedly harmless EMF exposures.

Okay. Now let’s get technical for a moment.

What Can You Measure with the Trifield TF2 EMF meter?

This Trifield TF2 measures 3 types of EMFs. You decide what type of EMF you want to measure by turning the selector switch on the front of the unit.

Magnetic And Electric Field Meter

When you switch on the Trifield TF2 and you turn the selector switch clockwise the first thing it measures are AC magnetic fields on the MAG setting. Then turn the selector switch another notch clockwise and it measures AC electric fields on the ELEC setting.

This means it can measure EMFs from things like:

  • electrical devices in your home: electric oven, electric hair dryer, clock radio, dishwasher, fuse box etc
  • overhead electrical powerlines and transformers
  • your home electrical wiring
  • electrical substation EMFs

Radio Frequency Meter

Most RF radiation these days comes in the form of packets of information or digital bursts. Whether it be GSM, LTE, WPA2, WiFi, Z-Wave or ZigBee the Trifield TF2 EMF meter can measure all these technologies.

This means it can measure EMFs from devices such as:

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

What Are The Most Important Features of The Trifield TF2?

There are 4 features I want to draw your attention to:

  • Perhaps the single most important feature of the Trifield TF2 is it’s tri-mode functionality. Some meters can only measure RF radiation. Others measure only magnetic fields. This EMF meter can measure magnetic fields, electric fields RF radiation.
  • What sets this EMF meter apart is that it has very good magnetic field functionality. This has always been the strength of the Trifield meters, and the tradition continues with this version.
  • The 3rd feature I want to draw your attention to is the vastly improved sensitivity in RF meter mode as compared to the previous version of this meter. It is much more sensitive.
  • This meter has a backlight so you can us it where lighting is poor and it has an audio function, so you get a notion of what the readings are without looking at the display.

Trifield TF2 or Trifield 100XE?

The Trifield 100XE has been one of the most popular EMF meters on the market for several years. There are 3 main reasons why this is so:

  • Very good magnetic field functionality for the price.
  • It was the first meter of it’s kind to introduce tri-mode functionality (3 meters in one).
  • Competitively price – often sold for under $120

But the TF2 is a vast improvement on the 100XE version. For several reasons:

  • RF mode sensitivity has been increased by one thousand times (the lack of RF sensitivity of the 100XE was it’s biggest failing)
  • Broader frequency range in RF mode. The 100XE could only measure up to 3 GHz. The TF2 can measure up to 6 GHz.
  • The 100XE is a an analog meter (old style needle display). The TF2 is a digital meter with a much more precise LCD display.

The Pros

What I like about the Trifield TF2 EMF meter:

  1. The main thing that I like about this meter is its tri-mode functionality, it can measure these 3 different types of EMFs. Some EMF meters can only measure one type of EMF – so its like having 3 meters in one.
  2. Its sensitivity. In MAG mode it’s got very good sensitivity and accuracy, it performs as well if not better than most other similarly priced meters because its 3 axis, and in ELEC mode it has good sensitivity too right down to 1V/m.
  3. Its ease of use. I’m a big fan of EMF meters that are easy to use, that you can just take out the box and use. This meter really does have a nice design which makes it particularly easy to use.
  4. The audio functionality. The old Trifield didn’t have this, many EMF meters still don’t but being able to hear the EMFs is a definite plus. It allows you to just move the meter around without looking at the display too much and you can tell by the sound if the EMF levels are high.
  5. Its price. It offers good functionality and good value for money for the price.

The Cons

  1. My biggest gripe is the sensitivity in RF mode. It has a resolution of 0.001mW/m2 (see comment below*) which is much much better than the previous version, the Trifield 100XE, but it’s still much less sensitive than the Cornet ED88Tplus for instance or the Acoustimeter.
  2. It only measures up to 6GHz. I would have liked it to have measured up to 8 GHz, given that with 5G etc the wireless industry is moving towards these higher frequencies and other meters, such as the Cornet ED88T and the Acoustimeter do measure up to 8 GHz.
  3. I don’t like having the 2 different modes, standard and weighted mode. I think its confusing. Just having standard or weighted modes would have made it easier to use.
  4. I don’t like having to go into the battery compartment in the back for the audio and the backlight. It would have been much easier if there would have been buttons on the outside to access these functions

(*The Quickstart guide I received with the Trifield TF2 was incorrect. It said that the resolution in RF mode was 0.1 mW/m2 when in fact the resolution is 0.001 mW/m2. This error has been corrected in the Trifield documentation – but my video incorrectly says the resolution is 0.1mW/m2.)

    What is your opinion of the Tenmars TM-196
    RF meter.
    I am looking to clean my environment up.
    THANK YOU for your help to all of us.

  • Lloyd Burrell said,

    Hi Bruce, the Tenmars TM-196 only measures radio frequency radiation. The Trifield TF2 can measure RF radiation, magnetic fields and electric fields. Just to be clear I’ve never tested the Tenmars TM-196.

  • Jodelle said,

    Thank you for the review. I have the Trifield 100xe and love it. My question about the TF2 is…. does it itself emit EMF since it’s more digital? Thank you for what you do!

  • Lloyd Burrell said,

    Hi Jodelie, in my experience EMFs from EMF meters is really not an issue. All these devices are battery operated…. they are very low EMF and they are used for short periods of time.

  • Ben said,

    Hi Lloyd,

    Thank you for taking the time to review the new meter. One thing that came to my attention was in the Cons section and in the video you mentioned the lack of sensibility in the RF mode which only measured to 0.1 mW/m2 but in the screenshot it shows three decimal places and you also write in the details section that the sensitivity is to 0.001 mW/m2. Is that a mistake or a different meter altogether? If so which meter is in the screenshot?

    All the best,

    Ben

  • Lloyd Burrell said,

    Hi Ben, I took the information about the sensitivity of the TF2, 0.1 mW/m2, from the Quickstart guide which came with the meter. Unfortunately there was an error. It should have said 0.001 mW/m2. Unfortunately I can’t change the video but I’ve now corrected this in the text. Thanks a lot for pointing this out.(My comments about the TF2s lack of sensitivity in RF mode still hold.)

  • Brenn said,

    But will it measure 5G millimeter waves? its not RF microwave…..

  • Lloyd Burrell said,

    Hi Brenn, millimeter waves (generally defined as upwards of 30GHZ)… currently I know of no EMF meters for general public use that can measure in this spectrum…. but it’s not surprising because the telecom industry is only just beginning to explore these frequencies.

  • David said,

    Hello Lloyd thanks for this review. It does not appear to be as much bang for your buck as you would get with the latest Cornet model. One bit of information which seems to be missing is the sampling rate. For the Cornet you mention 10000/s how does it compare to this one? Thank you

  • Lloyd Burrell said,

    Hi David, unfortunately the manufacturers do not publish information on the RF sampling rate… which is a shame.
