The Lornet 24 Non-linear junction detector is used for location and search of electronic devices, which are active or turned off.
The device works on the properties of semiconductor elements, second and third harmonics response to an RF probing signal.
In the practice when the semiconductor components are of artificial origin, they have a higher level of second harmonic. Semiconductor components of natural origin, such as oxide films, have a higher third harmonic level.
The NLJD 24 analyzes the harmonics responses of the radiated objects, and thus provides an accurate identification of electronic devices and natural oxide semiconductors.
This specific model provides the best receiving frequency channel free of noise and distortion, thus enabling investigations in electromagnetic environments.
Also, it automatically selects the RF probing signal frequency, such as noise levels, and then the digital processing of a demodulated signal gives max. sensitivity.
It comes with wireless earphones and a receiving device. It's design is thought for personal inspections, and by radiating power of 10 watts, it is fairly safe for the environment.
It detects hidden audio recorders, and at a low distance, such as 10-15 cm it is able to detect SIM cards.
