The Best EMF Meter For Detecting RF Radiation - Trifield TF2 VS Acoustimeter AM-10 - Best RF Meter?

Excellent info. Thanks, Matt.

But I've just tested my tf2 and I'm sat 15 ft away from my modem and it flickers like crazy🤔
0.8 to 3.7,so I'm not wanting to argue with anyone but everything you just said and showed is your tf2😳
Where did you buy it go swap it or try a different one, because like I say mine do not do what yours did not do😬

Battery in trifold almost dead!!

The RF antenna (but not the MAG or ELEC antennas) on the Trifield is directional. It’s placed on the top-left corner iirc, and you have to point it at whatever direction you want to measure. This is described in its documentation. You were measuring a few feet above the router.

So my wife and I have started grounding ourselves at night when we sleep. I just have a antistatic band hooked up to a extension cord only using the grounding portion of the power outlet. What’s the best way to test if the grounding is working on our body’s?

Something not right. The tri-field will almost never read zero, as shown, it will register above zero. The trifield might beb roken?

My meter work good

it does detect . The peak

Well , I just got the trifield , welp. What can I do with this one ? Any way to hack ?

I am trying to see if my car is spying on me, also, I did not turn on any thing or on-star

That poor fly!

I am not here to condemn your video, but the Trifield is not multi a directional tool. I think one of the commentors of your video stated this. Also you can correct me if I am wrong but the Acoustimeter measures in V/M and the Trifield for RF measures in milliwatts per square meter. If you look at the peak measurment at the top right of the Trifield device you will see it has a fluctuating number. This number seems to be a very close correct conversion of the rounded number readings on the Acoustimeter.

Should test for Formaldehyde off-gassing from the wafer board on the bedroom walls.

This device in proper testing using signal generators with pulses etc show this does not detect any radio frequency RF, buy another device that actually does

Thanks for the comaprison Matt ! Valuable info :)

First off, your battery is pretty low. As an amateur radio operator I have a responsibility to assure proper radiation and distance of my transmitter and antenna systems from myself and my neighbors. I have the same Trifield TF-2 in RF mode and sitting 10ft away from my WiFi router is showing solid ~3mW/m2 with the peaking at ~4.2mW/m2. I think you may have a defective TF-2. Maybe buy another one to test with.

looking up safe baby equipment. does anyone know if a battery operated baby swing emits harmful waves if the baby is close to it?

look at the battery strength on the TF 2 .....not really a fair test if the TF 2 has batteries that are just about dead

😂Can it Detect Ghost ! Video demo have !

I bought this item as a curiosity and to write a review piece online and it has definitely served that purpose. This in addition to the Trifield EMF meters are what got me started on this journey to expose the scam that are these EMF meters. It also was a nice hardware reverse engineering challenge to see if I could extract firmware from it, which I was able to easily do (with a Tag Connect TC2030-MCP 6-Pin Cable) and it loads nicely into Ghidra to see the scam that this device is pulling of which is very similar to the Trifield TF2. From what I was able to gather upon tearing down the device (which obviously the people who buy this product don't have knowledge of electronic components/systems) think of it as a crystal AM radio kit with very bad and poor attempt patch antenna using copper tape that is amplified with a bunch of audio grade amplifiers and fed into an analog-to-digital converter on a microcontroller (Microchip PIC18F46K42 in this case) and then the measurement is then converted to some number and displayed on the LCD and LED bar graph display.

Being the competent RF engineer that I am, I measured the VSWR of the copper tape antenna, and it is clearly not as wide band as claimed (It's only good mid-way through L-Band at 1500 MHz, with a VSWR pretty much at unity). This evidence clearly shows that the device is definitely not capable of measuring the claimed frequencies of 0.2 - 8.0GHz in a controlled way, as it's non-linear and you can't exactly calibrate that out with a lightweight microcontroller. This alone shows how much of a scam and money grab this meter is.

So this device (EMFields Acoustimeter AM11), is a scam that relies on the exploitation of people who fear technology and falsely believe that the tech is causing them ill effects... and also think that all RF is like nuclear radiation, which it is most definitely not. So basically this becomes the "confirmation-bias" meter that they can point to what they think the offending device and say "see it's that", when in reality they're seeing a signal amplified non-linearly anywhere from x100 - x10000 times its actual power level and then are falsely led to believe that they're health condition is not caused by other environmental factors and/or other underlying health problems. I'm also sorry to tell if you're looking to save $10,000 to $100,000 by buying the Acoustimeter instead of equipment from Keysight, Tektronix, Rohde & Schwarz, Teledyne-Lecroy, etc. you are only fooling yourself and are living in a different reality.

In conclusion, this was a fun experience and gave me closure that this whole device is scam and I feel validated as an engineer that works with RF and plays with $100,000 RF test equipment that can actually measure what this claims to measure. It confirms everything I suspected about the design of these meters and it's all just a scam that relies on the exploitation of people's basic fears of technology. If you really want to actually measure EMF, just buy a Keysight Field Fox and a Triaxial antenna (About $20,000).

So what is the best device to buy to test for overall EMFs, radiation and what not? I am super uneducated on this and don't know the exact differences in radio, electronic or magnetic frequencies and what is most dangerous. I don't want to spend a fortune to determine what places are best to sleep in my house to minimize radiation damage of all kinds. What is my best bet in that case?

Is it possible that the reason for the zero reading is this is an older meter, where the reading was wrong?
Found this on another video:
NOTE: At this time (Mar18) AlphaLab has let us know that a mistake was made with the placement of the decimal point in relation to Radio Frequency (RF) radiation measurement. The decimal point on the very first models needs to be 2 places to the left. Meaning: if the display reads 250.0, you should read that as 2.5 mW/m2. This would explain why the readings seemed so high in comparison to other meters. Glad they picked it up so quickly.

Why does my meter read higher when left alone on the bed pointed towards the router. As opposed to held in hand. Peak is 6.9 average

Does anyone know if the fly survived?

Hi All, I have measured some readings between 5000 - 15000 that is constant RF (peak) signal in my flat in Romford, UK! I really don't know how to rectify this, we have purchased the flat 2 years ago and I am feeling the effects of this radiation already! My question is - can i do something - like placing copper sheets in order to stop this or shall we all move out ASAP?

No disrespect but my TF2 has so far detected everything that it is suppose to. I can walk in any room and even outside and it gives me even small readings. I think you may have a faulty meter maybe. I put my TF2 8 ft from my router and it detected instantly and even my light bulbs it detected over a foot away 🤔

Did you take into account the fact that your batttery is nearly dead?

Electronic devices with very specific units of measure like EF, EMF in both magnetic and electric origin need at minimum 50% battery capacity in order to function properly.

There are certain devices with much higher sensitivity for certain frequencies & applications as you have and do mention, without question.

Good content and explanation for possible deviations so keep up the informative vlogs.

I’m watching on my phone 😺

Bro there's something wrong with your tf2 I am even further away from my wifi router and I am getting 0.104 bouncing back and forth it will go as low as a 0.080 at times

Crazy I had my tf2 just sitting on and its now bounced all the way up 0.700 same distance away from router wtf

Holy shit my whole house is just being slammed with rf frequency and I only have one wifi router some places its 3.040 it wasn't like that at first I had to have it on for 5 10 minutes and its not going down

Dude idk what is going on with you but my router is on the first story and I'm on the second story and opposite side of the house and getting readings as high as you are pointing right against the router from this far away. I'm only 2.4Ghz as well.

I want to test my PEMF mat strength. Also test my sleeping environment. Which would you recommend?

Make the videos and disable the comments. Problem solved

I just bought the Trifield TF2 and the RF is super sensitive. It picks up amazingly especially when I move my mobile phone near it, but even when my mobile is far away from it.

If the RF wave, the RF reading from the Trifield isn't strong enough move the needle from your sitting or sleeping location does it really matter? If it can't pick up any reading unless next to the source it's pretty useless for RF and was probably marketed just to increase sales. Until they are busted as in this video!

Sorry Sir, but you’re using this meter incorrectly.

Thanks Matt for making the video.

As all information/data is important to base a decision on.

So thanks again.

I'm not disappointed, actually impressed with the poor design

First, thank you to Amazon for changing the return policy on these kinds of devices, this was the only reasons for a number of years that I wouldn't buy these meters to call them out on their scammy and fraudulent claims.

I'm sorry to tell you that you're more likely to get skin cancer from the Sun and if unchecked that will metastasize to the brain (Yea you're more likely to get brain tumors from the sun than RF from your devices). I'm also sorry to tell if you're looking to save $10,000 to $100,000 by buying the Acoustimeter instead of equipment from Keysight, Tektronix, Rohde & Schwarz, Teledyne-Lecroy,, etc. you are only fooling yourself and are living in a different reality.

From everyone that seems to know EMFs, everyone says Trifield is the best on the market.

My meter goes crazy near the 5 g towers or the 5g pads on roofs of flats and held near my mobile it pulsates high and low it maybe because your battery is low or have you ever droped it because mine screams near a microwave or earbud headphones and ev cars charging there all high emf levels ?

He keeps talking as the top figure on left of the Trifield keeps going off.

neither of your links land on either of the acoutimeters

If you had even a basic understanding of non-ionising radiation it would help!

If you look closely at the top left of the Trifield's screen you can see the Peak levels, which more or less match the reading on the Acoustimeter.

I brought a trifield and its brilliant

I think you need a new battery mate.
