The original TriField ® Meter combines all the features needed for fast,
accurate measurements of electromagnetic fields. It independently
measures electric field and magnetic field, and is properly scaled to
indicate the full magnitude of currents produced by each type of field
inside a conductive body. As a result, it "sees" much more than any
other electromagnetic pollution meter. Depending on where the knob is
set, the meter detects either frequency- weighted magnetic fields (two
separate scales), or frequency-weighted electric fields in the ELF and
VLF range. It has significant sensitivity at 100,000 Hz, well past the
17,000 Hz horizontal scan of video displays. The radio/microwave setting
can detect up to three billion Hz (3 GHz), which lets you gauge radio-
wave power, CB and cellular phone equipment, and many types of radars.
Runs on a 9-volt transistor battery.
