Non-linear junction detector NS-11-900V

NS-11-900V Non-Linear Junction detector (NLJD) is a professional sweep device designed for inspection of constructional elements of building and interior objects in the premises.

The device is applied for detection and localization of covert surveillance electronic devices in different operational modes: transmission, switched off or stand-by mode (for remote controlled devices).

• High energetic potential;
• Able to search electronic devices covered by the metal net of reinforced concrete construction (basic distinction from compact NLJD NRm type)
• Protected against GSM/DECT interference.
