TriField TF2 Electromagnetic Field EMF Meter

The meter arrived in a few days and in perfect order. This very useful meter has just one big knob (no confusion possible!). You twist the big knob to measure magnetic (in milligauss) or electric field (in volt/meter) strength, or radio frequency effect (or density) (in milliwatt/m2). The magnetic and electric field strength can be measured standard, the real value so to speak, or weighted (that is: adjusted), according to disturbance (read: damaging impact) for live/organic organisms. The screen can be backlit and a tiny loudspeaker can give audio feedback. However the sound is very faint, barely audible. This meter capture and show you the very fast and short and, lo and behold, grotesquely strong RF pulses from your mobile phone or iPad. After this shocking discovery I now always put my iphone and ipad in flight mode when not in use. Then the meter is quiet and I feel safe and happy. It has also been a relevation to check on the microwave oven. When in use I now keep a good distance, a safe distance according to the meter reading. My comfy chair and bed is radiaton free according to the meter. : ) And since I have refused the installation of a smart wireless electricity meter I do not have that to worry about. (However the electricity supplier has inflicted upon me an extra yearly punishment fee of NOK 2000,- for my insubordination). (In my early career I watched colleagues warming their hands on RF leaking plugs and connections ...) Myself a retiree now, however with a university degree in applied physics and electronics and a working career in telecom/radiocom, the Trifield TF2 EMF meter is a true little beauty of simplicity and usefulness and it is therefore highly recommended for the amateur and the professional alike for easy everyday check and monitoring of your personal electromagnetic environment.

Great meter simple to use

Very good well made and accurate EMF meter.

Excellent EMF meter. Measures all 3 types of EMF radiation. Good to have to check over your home and make changes as necessary to help reduce amounts your body receives. Excellent value for money. Meter goes off the scale when near the 4G/5G phone masts even when you are in your car!

STANDARD MAG (Standard Magnetic Fields REGARDLESS OF FREQUENCY):- Power lines, appliances, wiring in walls, motors. Low EMF = Below 3m/3.0 (mG/milligauss). STANDARD ELEC (Standard Electric Fields REGARDLESS OF FREQUENCY):- Fluorescent lights, light-switches, sockets, electrical-switches. Low = Below 50 (V/m/volts per meter). WEIGHTED MAG (Weighted Magnetic Fields):- For higher frequencies which create more electric current in human body, eg. 60Hz = body receives field pulses 60 times per second. Power lines, appliances, wiring in walls, motors. Low EMF = Below 5/5.0 (mG/milligauss). WEIGHTED ELEC (Weighted Electric Fields):- Fluorescent lights, sockets, wiring, electrical-switches. Low = Below 50 (V/m/volts per meter). RF (Radio/Microwave Frequencies):- Phones, routers, ovens, radio/TV stations, masts, smart-meters. Low = Below 0.200 (mW/m2/milliwatts per square meter). For BRIEF PULSES of phones, routers, masts, smart-meters USE PEAK Measurement:- Low Peak RF = Below 1.000 (mW/m2/milliwatts per square meter).

Solidly built, reliable, easy to use and easy to read.

Love it. Such a cool piece of tech. Makes me feel like I'm in some old movie. Found out my sons bed is a active massively at night. His multi plug extention cable is touching his metal table, which is touching his metal bed and awning the frequency through his bed. Not just by touch, but by a field of energy closer around the table. Turn off the plugs and it goes. Move away from the table and it goes. Very interesting to see these things that your eyes wouldn't believe exist.

This was one of the best recommended by someone who actually uses these. Bought to check out a house (for my daughter with a young baby) pre-purchase as a mobile phone mast was nearby. Readings showed you would not wish to live in the road(!), but inside the house was OK. Very helpful. Now proceeding with the purchase.

Easy to use and readings seem accurate and consistent. Well built, sturdy and reliable device. Without knowing much in this field, this device was easy to use with consistent results. If you using to assess your home , you could get away with hiring one as it’s quick to work out what is a problem etc .

Initial experimenting shows it works well right out of the box, and battery was already installed, even. All seems to work great!

Das Gerät ist im Vergleich zu den anderen Angeboten etwas teurer, aber auch deutlich besser. Die Messwerte sind plausibel und reproduzierbar. Das Gerät hat sehr schnell reagierende Sensoren und erfasst gepulste HF Strahlung wirklich gut. Perfekt zum Aufspüren von elektromagnetischen Strahlungen. Wer einen wirklich funktionierenden Detektor sucht, wird hier fündig. Die Grenzwerte sollte man bei der KI erfragen - da gibt es unterschiedliche Auffassungen. Nebenbei eine tolle analog anmutende Bedienung (ich liebe richtige Bedienknöpfe).

I really like this meter. Seems to be very accurate. One thing that would be great if they would add would be some kind of an ability to look at history. RF frequencies are very difficult to kind of track down and they come and they go. One thing that this does, it tells you the peak and then it also tells you the average, which is very helpful. But when when the levels change so much it can be a little overwhelming to get a handle on it so that’s why I suggest some kind of a history where you could look at maybe a period of several minutes and take the average over that timeframe. Download it and analyze it. But other than that, the device is great. One other thing I would suggest to the company is that they add some kind of a handle or a grip to the to the meter because it’s a little slippery and I have to be careful that I don’t drop it. There’s a few other minor things but overall I think it’s a great meter.

Given our dependency on technology (and because I'm a crunchy granola hippy), I thought it'd be interesting to see the EMF levels in our house and the surrounding neighbourhood to ensure we are not being zapped. Things to keep in mind: we live in India. Our house is a farm house in a semi-rural area, but is quickly urbanising. Our home is constructed of thick cement that honestly rivals a WWII bunker. It's my understanding people should not be exposed to more than 60 V/m (the standard ELEC setting) and 1 mW/m squared (the RF setting). What we discovered is this (and what the pictures hopefully illustrate): --My cell phone, which is an Apple 8 and generally connects to either the WiFi or LTE when using cell service, had a very high reading on RF, and it would frequently max out the reader. Most of the time it got 6-11 and up to 20 mw/m when the call was connected, and 2-3 when not connected. It was at .2-something when in airplane mode. Best to keep calls to a minimum, hold the phone away when connecting, either keep the call short or hold it on speaker phone when talking, and then put it in another room when done. RF is negligible when the phone is far away, so that's good. --Electrical outlets are really high at 400 V/m when switched on, to the point that it's advisable to switch off all outlets when not in use or when not needed. This is especially true if you sleep next to power outlets due to the positioning of the bed. --Though this is the case, the V/m drops considerably when one backs up even just a few feet. So, even just moving furniture a few feet away from outlets can help significantly. --Laptops should never be used when plugged in, because the EMFs were off the charts--it often topped out the reader went to insane levels of 900-1,000! I had no idea how dangerously high my computer got when connected to a power source, and now I will absolutely not use my computer on anything other than battery. In fact, I will be willing to replace the battery in my machine when it gets depleted, rather than use it plugged in. I wish I knew this earlier, as my previous laptop HAD to run from a power source on account of the battery being exhausted. I had used it this way for years, yikes! When on battery, no EMF levels were detected. --Our router showed 262 V/m. It too dropped when one moved away, to the point that where I sit the next room over, I have a reading of 0 V/m. --My husband's work station has a number of computer screens, a wireless mouse, wireless keyboard, tons of wires, and he loves his gadgets. He sits next to the router. With all these things, his station is 260 V/m at chair level, worse when he moves closer to the offenders. I'm trying to convince him to rejig his office. --The large yard enclosing our house (and most houses, I imagine) reads 0 V/m. --When leaving our house to walk along the road strung with electrical poles (as we do in the evenings), the reading is 60 at my head height and 70 at my husband's. When I hold the reader as high as it can go, the reading as 120+ V/m. The reading is 120+ at head height when walking past the transformers and junction boxes. I'll be rethinking the walks up and down the road, for sure. --On the second floor, the reading is 0: this is good, considering that the poles get more intense with height. Thankfully the house seems far enough away to put the influence of these poles to null. I can edit this review and include more info when we visit our flat in the heart of the city, to see if that makes a difference. Hopefully this helps either persuade someone to buy the product or be mindful of the things I learned. So yeah, great product, definitely worth the spend for the information it provided. Very easy to use.
