Description:
DT-830 is a new type of thermal imaging non-linear junction detector, which integrates the functions of thermal imaging and non-linear junction detector. It can detect electronic devices hidden in walls, floors, ceilings, lamps, furniture or containers, as well as judge the appearance of hidden electronic products, so as to facilitate rapid and accurate judgement by inspectors and improve the efficiency of security inspection. By means of thermal image display, vibration and sound prompt, the NLJD detector can quickly locate the hidden target.
Application Scenarios:
DT-830 thermal imaging 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 detonators, remote controllers, etc.
Personal Privacy Protection: Hidden cameras and surveillance devices such as recording pens, cameras, etc. in residential buildings and hotels.
Features:
-
Fast Judgment of Hidden Object Types: Through thermal imaging function, we can quickly and intuitively judge the appearance of the electronic products under surveillance, and help the inspectors quickly judge the types of hidden electronic items.
-
Strong Semiconductor Recognition Ability: Built-in spectrum analyzer supporting second and third harmonic detection can quickly and effectively identify devices and devices containing semiconductors.
-
High Sensitivity: In particular SIM card devices have a high density of intelligence, which ensures that secret books and mobile communication devices can be quickly detected.
-
Low False Positive Rate: The built-in optimized radar detection algorithm greatly improves the NLJD’s detection capability, and the false alarm rate is very low.
-
Safe and Reliable: The characteristics of DT-830 Non-linear Junction Detector meet the requirements of electromagnetic radiation and are absolutely safe to the human body.
-
Flexible and Simple Operation: The interface of this NLJD is simple and intuitive, the keys are few and concise, and it is easy to operate manually.
