SEL‑601M magnetic field detector

The SEL-601M magnetic field detector can detect operating electronic devices designed to obtain information, for example, such as:
— radio microphones, voice recorders, radio stethoscopes, telephone radio repeaters;
— hidden video cameras;
— unauthorizedly activated mobile and other wireless phones, radio transmitters;
— radio modems and digital wireless access systems;
— beacons of tracking systems for monitoring the movement of objects.

The SEL-601M magnetic field detector detects low‑frequency emissions, operating in the frequency range of 0.04–30 kHz, which makes it possible to identify listening devices even in shielded casings. Signal reception is carried out by a built‑in magnetic antenna.
