Trifield TF2 - Tri-mode meter


Trifield TF2Trifield TF2 ---- $179.90  (Worldwide Free Shipping)
3-Axis Magnetic/1-Axis Electric/1-Axis RF field meter

New improved digital Trifield ® Meter measures all three types of electromagnetic field: AC magnetic field, AC electric field, and radio (including microwaves) now with high sensitivty. The magnetic detector is 3-axis, making the meter easier to use than comparable 1-axis meter.
Now with backlight and sound.

  • Detects the three type of electromagnetic pollution: AC magnetic fields, AC electric fields, and radio/microwaves.
  • AC magnetic fields is 3-axis, allowing quick accurate readings regardless of meter orientation.
  • Two magnetic and electric modes for weighted and non-weighted measurements.
  • AC magnetic fields between 0-100mG. This is sufficiently sensitive to detect the background field almost anywhere (except for from civilization), while measuring up to very strong AC fields.
  • Electric range covers 1-1000 V/m.
  • Radio/microwave covers 0.001 to 1000 mW/m2 for frequencies between 20MHz - 6GHz. 
  • Operates about 20 hours without backlight or 12 hours with backlight using a replaceable standard 9V battery, has a low battery indicator.
  • Large digital display.


  • Measures AC (artificial) magnetic fields rapidly. (Does not measure DC of static fields, such as the Earth Field. Click here for other magnetic meters).
  • Measures AC electric fields rapidly, such as from overhead power lines or improperly grounded equipment. Can locate wiring in walls.
  • Measures major RF/microwave sources such as leakage from microwave ovens, or the field near cell towers, smart meters, Wi-Fi and similar.
