With an easy-to-read ’traffic-light’ display, it helps you detect and measure magnetic fields (in nT) from electrical sources.

Handy, pocket-sized magnetic field monitor with 10 colored LED lights providing measurements in nanotesla, from 0 - 2400 nT. Ideal for all magnetic fields from electrical sources at operating at frequencies between 20-1200 Hz, which includes normal mains electricity at 50/60Hz.

It displays field strengths between 0-2400 nanotesla, with scale points (LEDs) at 100, 150, 200, 300, 400, 600, 800, 1200, 1600 and 2400 nanotesla, which are further grouped into bands of green, yellow, and red.
