DT-820Plus is an upgraded model of DT-820 with over 1m telescopic rod. It is a professional portable non-linear junction detector at good quality and performance. DT-820Plus NLJD can detect electronic devices hidden in walls, floors, ceilings, lamps, furniture or containers, whether they are transmitting signals or switching on or off. Once there is alarm, operator will be alerted by display, sound and vibration. This is a top-level TSCM equipment. This nljd detector can be used to find target invisible equipment for protecting organizations and individuals Private information. DT-820Plus portable non-linear junction detector comes with an extendable pole for longer-distance inspection such as ceiling surveillance.

Technical Principles:

This portable Non-linear junction detector emits S-band fundamental wave to the target area or object, and the receiver captures the second and third harmonics generated by the target object. Artificial intelligence algorithm is used to analyze the harmonic law, so as to detect and identify the electronic devices with non-linear junctions.

Application scenarios:

DT-820plus portable non-linear junction detector can be widely used in government, public security, prison, justice, army, education examination, business security and personal privacy protection, etc.

Business Safety: Detecting unauthorized electronic devices, such as eavesdroppers, mobile phones and devices with SIM cards, hidden in company board rooms or secret offices;

Public Safety: Detecting electronic devices hidden or prohibited from use in safe areas, such as detonating devices, remote controllers, etc.

Personal Privacy Protection: Detecting hidden cameras and surveillance devices such as recording pens, cameras, etc. in residential buildings and hotels.

Non-Linear Junction Detector Application Scenerios

Features:
