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; sometimes called nnEMF). 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.

Features:

  • Detects all three types of EMF / nnEMF 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

Specs:

  • AC Magnetic Field (3-Axis)
    • Frequency Range: 40 Hz to 100 kHz
    • Range / Resolution: 0.1 to 100.0 mG (resolution: 0.1 mG)

    • Sensor: 3-axis for true magnitude readings regardless of orientation [1, 2, 3, 4]

  • AC Electric Field (1-Axis)
    • Frequency Range: 40 Hz to 100 kHz
    • Range / Resolution: 1 to 1000 V/m (resolution: 1 V/m)
    • Accuracy: ±5% @ 50/60 Hz
    • Features: Standard or frequency-weighted responses (weighted mode emphasizes effects on the human body) [1, 2, 3, 4]

  • Radio Frequency (RF) / Microwave Field (1-Axis)
    • Frequency Range: 20 MHz to 6 GHz (covers 4G, most 5G, Wi-Fi, Bluetooth; excludes experimental millimeter waves)
    • Range / Resolution: 0.001 to 19.999 mW/m² (resolution: 0.001 mW/m²)
    • Response: Unweighted, refreshes 4 times per second with peak hold for digital pulses [1, 2]
