ORION™ HGO-4000 Non-Linear Junction Detector

Research Electronics International, LLC (REI) is one of the world’s leading manufacturers of Electronic Detection and Testing Equipment for Security Applications.

Based in Cookeville, Tennessee, USA, REI specializes in Radio Frequency (RF) Detectors, Non-Linear Junction Detectors (NLJDs,) Telephone & Line Inspection Equipment, Audio Security Equipment (including Acoustic Noise Generators,) Video Inspection and Physical Inspection Equipment to locate Electronic Bugs or Eavesdropping Devices.

CSSPakistan in proud association with REI LLC brings you ORION™ HGO-4000 Non-Linear Junction Detector.

Locate Listening Devices and Semiconductors

The ORION HGO-4000 is REI’s original high gain Non-Linear Junction Detector for special applications. The ORION HGO-4000 can locate listening devices and semiconductors in walls floors, ceilings, fixtures, furniture or containers and provides a user the capability to detect hidden electronic devices, regardless of whether the device is radiating, hard wired, or even turned off.

Efficiency: high transmit power for rapidly searching large areas and the circularly polarized antenna reduces search time and improves reliability

Usability: second and third harmonic operation includes advanced algorithms for minimizing false alarms as well as listening capability for each harmonic

Portability: balanced, ergonomic, lightweight design with no cables or bulky transceiver units to carry
