Trifield EMF Meter - Model TF2

The TriField EMF Meter Model TF2 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. 

Additional Features:

  • 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


  • 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
