Non-Linear Junction Detector
Model: HW-24
The non-linear junction detector “HW-24” is used for search and location of electronic devices both in active and switch-off state.
It is highly competitive with most popular models of non-linear junction detectors. It can operate in continuous and pulse mode as well, having a variable power output. Automatic frequency selection allows operation in complex electromagnetic environment.
The detector generates a response at the 2nd and 3rd harmonics when radiated by an RF probing signal. Semiconductor components of artificial origin will display a higher level on the second harmonic while corrosive semiconductor components of artificial origin will have a higher level on the third harmonic respectively. An “HW-24” analyzes the 2nd and 3rd harmonics response of the radiated objects, which enables a quick and reliable identification of electronic devices and corrosive semiconductors.
The “HW-24” automatically finds the best receiving frequency channel free of noise and distortion providing flawless operation even in the complicated electromagnetic environment.
Its power output is harmless to operator’s health. Operation at higher frequencies makes it in some cases more efficient than detectors with standard frequencies but with greater power output.
