Product Description
The non-linear junction detector LORNET-0836 is the indispensable tool for quick and reliable detection of devices containing semiconductor components. It can be used for counter-surveilance search works in premises (covert transmitters identification), as well as for location of explosive devices outdoors. The DPF (double probing frequency) technology with a patent pending antenna system places it truly apart from the competition.
Main competitive advantages:
• Duoble probing frequency operation mode gives significant advantages over single frequency NLJD since it is much better to detect small-sized and high-frequency semiconductor objects at high frequencies whereas the use of low frequencies benefits from improved detection in the wet ground and concrete walls;
• It is possible to operate in one of the frequency ranges and in both of them simultaneously;
• An embedded parabolic antenna with high gain (20 dB at 3600 MHz) enables highly precise detection of semiconductor components from a long distance.
• Laser pinpointing for a space selective object localisation;
• Wide power control range, automatic and manual modes of probing signal level adjustment;
• Possibility to listen to the envelope detector output as well as to the received signal level via a built-in loudspeaker and wireless head phones to evaluate parametric impacts (e.g. knocking) on the suspicious object.
• Low-frequency range (800 MHz) gives opportunity the operate high humidity.
• High frequency range (3600 MHz)gives opportunity to spatially select the semiconductor elements location
• Reliable detection of the SIM-card at a distance of 80 centimeters.
• Compact device, the weight is 1 kg.
• Lornet is equipped with an automatic system of protection against centered jamming by criterion of a minimum noise in the receiver path of the 2nd harmonic.
• Electromagnetic radiation towards the operator is many times less than one setted by the Regulator.
