ORION™ 900 HX Non-Linear Junction Detector

ORION™ 900 HX 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™ 900 HX Non-Linear Junction Detector.

Locate Hidden Electronics

The ORION 900 HX Non-Linear Junction Detector (NLJD) detects electronic semi-conductor components through dense materials such as bricks, concrete, and soil. The ORION 900 HX NLJD is made to detect and locate hidden cameras, microphones, and other electronic devices regardless of whether the surveillance device is radiating, hard wired, or turned off.

Efficiency: longer 900 MHz wavelength does better at detecting older, less refined circuitry and also penetrating building and construction materials

Usability: touch screen display provides fingertip control of operation settings and graphic displays which can be captured and saved for historical reference and reporting

Portability: lightweight design is under four pounds and no tools are required with the integrated telescoping pole

Technical Specifications

1. Features

  • Digitally modulated spread spectrum transmit signal provides increased detection range and interference rejection
  • A 1.25 MHz-wide transmit signal increases detection sensitivity
  • Histogram graph displays continuous history of harmonic response and power adjustment
  • Touch screen displays the full RF spectrum for transmit, 2nd, or 3rd frequency ranges
  • The adjustable, high gain provides increased detection range for the same power
  •  A 2nd & 3rd harmonic response correlated to Tx improves detection and minimizes interference
  • Visible display, alert tones, and haptic (vibration) alert can be selected to alert on detection
  • Telescopic pole extension allows a user to search ceilings and walls
  • Synthesized transceiver provides frequency stability and agility to automatically search for quiet operating frequencies
