LUX - non-linear junction detector
Non-linear junction detector "LUX" is designed to detect various kinds of electronic devices containing semiconductor elements, such as eavesdropping devices, audio-recording devices, and remote control devices etc., both in switched-on and switched-off modes.
"20 К" mode allows listening to low-frequency signal of a working electronic device (tape recorder, radio transmitter, microphone amplifier).
Distinctive features:
1. Single-body construction consists of antenna unit and an extending arm where receivers, transmitter and processing unit are placed.
2. Possibility to connect headphones.
3. Non-linear junction simulator is included in delivery set.
4. Small size, ergonomic design, weight is low as 1.3 kg make the detector capable for work in hard-to-reach places.
5. Adjustable power output and sensitivity.
