This is an important device that can quickly and reliably detect semiconductor devices.It is mainly used by special department staff to perform inspections on various indoor spaces to check suspicious targets and semiconductor devices in unknown packages or objects,such as bomb detonators or bugs,and can also locate outdoor explosive devices.This detector can automatically adjust the receiving frequency to avoid external noise interference,so as to ensure good detection results in complex geomagnetic environments.The built-in high-frequency antenna of the device ensures that semiconductor components at a relatively long distance can be accurately detected,as far as 10 meters.The unique laser positioning technology increases the accuracy of positioning.The high-frequency detection signal enables it to have a longer detection distance than ordinary nonlinear node detectors.The device has high detection power,large detection head area,and sensitive reception,and has been widely recognized by users in practical applications.
