LUX Non Linear Junction Detector (NLJD)
Mode “20 K” allows listening to the low-frequency signal of an operating device, a tape recorder, radio or microphone amplifier and is a powerful tool for obtaining better information about the type of nonlinear device (bug) being detected. In this mode, signals at frequencies of harmonics received by the unit, are modulated by a low-frequency signal existing in the electronic circuits of a device.
For parameters such as work safety (radiation in the opposite direction), continuous battery operation time, fast deployment and ergonomics, etc. The LUX detector surpasses other equipment on the market. This is ensured by the original circuit and design solutions.
RESOLUTION: The resolution of each LED indicator is 3dB and the received signal can also be heard with the accompanying earphones.
AUTOMATIC SELECTION: The system automatically selects the best frequencies (not interfering with GSM range) allowing the surveillance bug detector to work in a concentrated environment.
ADJUSTABLE: The LUX Non-Linear Junction Detector’s transmitter power can be adjusted as well as the receiver’s sensitivity.
CAPABILITY: The LUX operates in pulse mode with a radiated power of 25 watts per pulse, this allows for higher (-120 dbm/-150db/W) sensitivity of the receivers. Therefore the LUX matches or exceeds the most powerful current Non-Linear Junction Detectors (NLJD) available. This is achieved by optimizing the parameters of the signal in conjunction with a superior antenna system.
UNIQUE DESIGN: Ergonomic and light (1.3 kg including battery) with extendable/retractable poll inside the handle for superior reach, also the surveillance equipment detector’s innovative screw-in battery extends the handle further.
USAGE PARAMETERS: Operation speed, product safety, ergonomics, battery and continuous usage time (not less than 5 hours), the LUX meets and even exceeds current NLJDs on the market.
