The TriField EMF Meter is an AC gaussmeter, AC electric field meter, and radio power density meter in a single unit, that combines all the features needed for fast, accurate measurements of electromagnetic fields (EMF). In addition to standard AC measurement modes, a special frequency weighted mode will properly scale the magnetic and electric measurements to indicate the full magnitude of currents produced by each type of field inside the human body. 9V Battery required.

Please be advised that the Trifield meters are quality control tested prior to packaging and cannot be returned once opened and used. If you wish to use the meter for a short period of time, please see our hire option. 

Please read the instruction manual or view the YouTube video below on how to use the Trifield meter before purchasing.


  • Detects all three types of EMF pollution: AC magnetic, AC electric, and RF/microwave
  • Special frequency weighting mode for measuring electric current from EMF in the human body
  • AC Magnetic Mode covers 40 Hz – 100 kHz with range of 0.1 – 100.0 milligauss (mG)
  • AC Electric Mode covers 40 Hz – 100 kHz with range of 1 – 1000 volts per meter (V/m)
  • RF Mode covers 20 MHz – 6 GHz with range of 0.001 – 19.999 milliwatts per square meter (mW/m2)
  • AC magnetic measurements are 3-axis, allowing for quick readings, regardless of meter orientation
  • Large liquid-crystal display (LCD) for crystal clear, accurate readings
  • Adjustable backlight for use in low-light environments
  • Audio Indicator emits sound that helps to pinpoint EMF sources
  • Peak Hold captures fast pulses, for measuring fast digital signals
  • Operates for more than 20 hours on a 9V battery, with a low battery indicator
  • The TF2 measures up to 6 GHz and so that includes the tower to phone radiation 5G works on (3.5 – 3.6GHz) 


  • Mobile phone and cell tower RF radiation
  • Smart meter RF radiation
  • Wi-Fi router and Bluetooth RF radiation
  • Overhead AC power line and transformer EMF emissions
  • Laptop, refrigerator, circuit breaker box, etc. appliance EMF emission
  • EMF emission inside aircraft and motor vehicles
  • Microwave oven leak
  • Location and EMF of wiring in walls
  • EMF from plumbing pipes used as grounding

Trifield EMF Meter

Great little instrument, did the job by responding to emissions of the electric meter box, router, lights and other items like power points. Now what to do with this problem.

Emf meter

Great to use. Interesting to find what is in the air all around us, and how things change when you power off.

Useful Tool

Easy to use, handy to take anywhere you encounter electric fields or radio frequencies, which is just about everywhere in this day and age. I was surprized how difficult it was to remain in safe levels in any electrified building. I highly recommend this scientific instrument, especially if you care about the health of you and your children.

Trifield TF2 EMF meter

Very good service from Aussie Security Products, fast shipping and meter worked as reviews said it would, find it very easy to use and I'm shocked over some readings, now I just need to find accurate info regarding what is the damaging number of magnetic, electric and RF reading zero would be nice but measured over 50 with magnetic, electric I had the meter go to max as well as RF guess that is not good for any length of time. Will buy more products from Aussie Security Products :-). I could give this meter 6 stars if the peak number displayed would have larger numbers also only goes to 6Ghz however this is enough in most cases and you do not pay too much either, excellent product!
