Non-linear Junction Detector FY-811
Description
Description
Enhanced Nonlinear Junction Detector integrates a wireless signal detection unit on the basis of the nonlinear junction detection unit. It can detect electronic devices concealed in parcels, walls, floors, ceilings, lamps, furniture or containers, regardless of whether the devices are powered on or in operation. Meanwhile, based on the differential detection principle, it can accurately locate suspicious devices, reduce recheck costs and improve the speed of work response.
Functional Features
1)Authoritative Certification
Passed the test and certification of the First Research Institute of the Ministry of Public Security, and complies with the industrial standard of GA 1236-2015 for Nonlinear Junction Detectors.
2)High Sensitivity
Equipped with a built-in high-gain antenna, the receiving sensitivity is as low as -140dBm, enabling rapid identification of semiconductor-containing devices concealed in walls or furniture.
3)Precise Positioning
Based on the differential detection principle, it can accurately locate suspicious devices.
4)Long Battery Life
A single battery supports over 4 hours of continuous operation, meeting the demands of a single detection task.
5)High Cost-Effectiveness
As an integrated detection device, it reduces the cost of secondary rechecks, greatly improves detection efficiency while cutting down overall expenses.
6)Strong Detection Penetration
It features the detection capability to penetrate brick walls up to 370mm thick, complying with the Class C product specifications stipulated in the GA 1236-2015 standard.
