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 (using the 100XE version).
Measures major RF/microwave sources such as leakage from microwave ovens, or the field near cell towers. (Note that wireless internet transmitters and individual cell phone are designed to emit very little power and usually are well below international RF exposure threshold. Consequently, the Trifield Meter will only detect these if very near the source.)
Standard Version Frequency Weighting: *Sensitivity is proportional to frequency from 40 Hz to 500 Hz; flat from 500 Hz to 2000 Hz*Sensitivity is inversely proportional to frequency from 2K Hz to 100K Hz
Flat Frequency Version:+/- 20% from 50 Hz to 500 Hz; inverse frequency above 500 Hz
AC Electric Fields:(3-axis; however, note that E-field is affected by the body position)
Frequency Range:40 Hz – 100 K Hz (see frequency weighting)
