Product Description

High sensitivity Junction Detector 1.5Kg with 2.4GHz frequency band




  To ensure secrets security of some important place like government department. Our company developed the latest generation junction detector called ZD-JD007 junction detector. It works at 2.4GHzable to detect any electronic device hidden in walls, floors, ceilings, lamps, furniture or containers. It applies our advanced harmonic signal detection technology and has high sensitivity less than -135dbm. Where these electronic devices are transmitting singers or not, they are detected and alerted by display, vibration and sound prompts. Then detector can focus on hidden targets. Also, the detector has light weight of 1.5Kg and can be carried by user easily.



Application scenes

1. Government Secrecy Department such as public security, justic, prisons, education, troops, and so on.

2. Cheating Prevention In Education Industry Examination

3. Security inspection of large scale activities

4. Confidentiality Inspection of Commerical Organizations


Product Characteristics

  • Strong semiconductor detect ability: With the 2nd and 3rd harmonic signal strength detection technology, it can quickly and effectively identify device and semiconductor materials inside it.
  • High sensitivity: The junction detector is equipped with built-in high gain antenna to achieve high sensitivity less than -135 dbm. It has long detection distance especially for SIM card devices. To ensure secret, mobile communication equipment will be detected quickly.
  • Friendly interaction interface: Support visual graphical interface, bright display of power emission level, 2nd and 3rd harmonic graphics, easy to operate.
  • Low false alarm rate: The built-in nondestructive detection algorithm greatly improves the detection ability, and the false alarm rate is very low.
  • Safety and reliability: The characteristics of equipment meet the requirements of electromagnetic radiation and are absolutely safe for human body.
  • Flexible operation: The interface is simple and intuitive, with few buttons and easy manual operation.
  • High cost performance: The most cost-effective, cost saving and excellent performance in the world.
