Product Introduction:
The NR-900EMS nonlinear node detector is used to search for hidden eavesdropping devices, detonators, and other similar devices containing semiconductor components. It may be: radio microphones, audio amplifiers, wired microphones, infrared or ultrasonic data and control channel devices, recording recorders, detonators, etc., and can be accurately positioned regardless of whether the object of inspection is on, standby, or off.
The NR-900EMS nonlinear node detector can receive both secondary and triple harmonic signals, making it easy to detect semiconductor components and metals in hazardous materials. Widely used in public security, special police, armed police, prisons and the podium, leading residence and other security activities, this product is nR-900EM upgrade products, performance is better than NR-900EM.
