This Non-linear junction detector is designed to detect various kinds of electronic devices containing semiconductor elements (diodes, transistors, circuits), such as eavesdropping devices, microphone amplifiers, radio frequency bugs, audio-recording devices, remote control devices, improvised explosive devices etc., both in switched-on and switched-off modes.

Lightweight and compact construction of the detector ensures comfort of operation. This Non-linear junction detector is intuitive and simple to use. Results of analysed harmonics are presented in form of bar graphs on a graphic LCD screen. A set of wireless headphones greatly facilitates the work – it notifies the operator with acoustic alarm about detection of potential threats. Automatic frequenct adjustment allows to operate in electromagnetically diverse environment. Apart from conducting radiation analysis, This Non-linear junction detector simultaneously adjusts optimal working parameters.

Key features:

• Detection of small devices such as SIM cards possible due to use of high frequencies,
• Precise location of electronic devices ensured by narrow, directional characteristic of the antenna, and a laser pointer,
• High sensitivity and selectivity, together with long detection range ensure great efficiency of work,
• Regulation of duty cycle in passive mode – manual or automatic,
• Ergonomic and easy to operate,
• EM radiation affecting operation of other devices (e.g. mobile phones, WiFi networks) in a minimal degree,
• Efficient battery of the Non-Linear Junction Detector allows up to 3 hours of operation.
