Lornet-36 - Non-linear junction detector

The non-linear junction detector LORNET-36 is the irreplaceable device at carrying out of operational and search activities in premises with high density of subjects containing electronic devices and also by search of small-sized electronic devices (1х2cm). The device is also effective during remote analysis of suspicious objects for the presence of electronic components at a safe distance of 3-5 meters.

Main competitive advantages:
  • Thanks to high frequency of probing signal and effectively implemented narrow diagram of antenna directivity Lornet-36 detects semi-conductor elements hidden by various materials (can be detected through the cracks, unearthed screens, through reflection from smooth surfaces, SIM-card is detected from distance in 1 meter, etc.).
  • Narrow beam of directivity diagram and presence of the laser index allows carrying out spatial selection of various semi-conductor elements with split-hair accuracy that is extremely important characteristic at the analysis of suspicious subjects within safe distance.
  • Automatic and manual changes of capacity of probing signal in pulse mode.
  • Usage of the newest technologies and materials, ergonomics. Convenient bodies of indication and management, simple in work, small weight.
  • Electromagnetic influence on the operator is essentially lowered.
  • Wireless head-phones.
  • High frequency range (3600 MHz) gives opportunity to spatially select the semiconductor elements location.
  • For efficient identification of artificial and natural semiconductors a listening through a built in speakerphone or headphones can be used after AM decoding of the signal in continuous mode. • 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.
