TriFieldTF2 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.

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!

Works well, not too difficult for an old lady to understand, set my mind at rest regarding EMF's and smart meter output.

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 USEPEAKMeasurement:-Low Peak RF = Below 1.000 (mW/m2/milliwatts per square meter).

Excellent piece of scientific kit.

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.

It was easy to use, good design, good meter read out display dial etc and alarm function good. Was able to find why my sleep pattern was poor and change wifi set up and sat view recorder /Tv mobile to different connections and switched off at mains, was a great improvement.in same room. Also tested phone mast & Towers around my area and found some of reading 10x ( peaking at 15 x) over the safety limit specified in the supplied manual.??.

Arrived well packaged and fully sealed. Within the ample Amazon packaging the unit itself was manufacture sealed within a shock proof case. When I put the 9v battery in the unit it was completely dead, I went out and bought another battery and tried it again, unit was still lifeless. There was no damage to the packaging or to the unit itself. This is an expensive meter, so I have to question the build quality of the meter itself, how did a dead unit get past quality control or how did it break during basic transportation, after all it’s supposed to be a handheld portable device, so should be reasonably robust. I’m not confident about buying another one, it was an ordeal returning it and expensive. This was a manufacturing issue not an Amazon issue.
