Product introduction:

　　A new domestic Nonlinear Junction Detector can detect any electronic devices hidden in walls, floors, ceilings, lamps, furniture or containers, regardless of whether these electronic devices are transmitting signals or not, and whether they are on or not, it can be alerted in various ways, such as through displays, vibration and sound prompts, so that the operators can focus on the hidden targets. 

　　Technical principle:

　　The Nonlinear Junction Detector(NLJD)antenna head is a transceiver(transmitter and receiver)that radiates a digital spread spectrum signal to determine the presence of electronic components.When the energy encounters semi-conductor junctions(diodes,transistors,circuit board connections,etc.),a harmonic signal returns to the receiver.The receiver measures the strength of the harmonic signal and distinguishes between 2nd or 3rd harmonics.When a stronger 2nd harmonic is represented on the display in red,it indicates an electronic junction has been detected.

　　Application：

　　It can be widely used in government,public security,prisons,justice,commercial security and personal privacy protection,etc.

　　Corporate trade secret protection: detecting unauthorized electronic devices hidden in important company meeting rooms or confidential offices ,such as bugs,cell phones and devices containing SIM cards;

　　Public safety protection: Detecting electronic devices hidden or prohibited within safe areas, such as Explosive device, remote controls, etc;

　　Personal privacy protection: hidden in homes,hotels and other places of clandestine photography and recording devices,such as voice recorders,cameras and so on.

　　Features:

　　High positioning accuracy

　　The product adopts 2400MHz radio frequency detection technology and has high positioning accuracy.

　　Good identification skills

　　Built-in spectrum analyzer that supports second and third harmonic detection, which can quickly and effectively identify devices and equipment containing semiconductors.

　　Highly penetrating

　　With the ability to penetrate the bullet layer of 370mm brick wall,there is no place to hide the steganography equipment.

　　High sensitivity

　　Especially for SIM card equipment, it has high sensitivity to ensure that secret records and mobile phone communication equipment can be quickly detected.

　　Low false alarm rate

　　Built-in non-destructive detection algorithms dramatically improve detection capabilities with very low false alarm rates.

　　Harmlessness

　　Equipment is meet HJ/T10.2 radiation environmental protection requirements,safe and harmless to the human body

　　Flexible and easy to operate

　　The interface is simple and intuitive, with few buttons and easy for manual operation.
