Product introduction:

　　A new domesticated 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 detectors 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 meeting rooms or confidential offices of the company,such as bugs,cell phones and SIM card-containing devices;

　　Explosive discharge for public security special police:detecting electronic explosive devices and remote controls in dangerous areas;

　　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

　　Adopting 2400MHz RF detection technology,featuring high-precision localization.

　　Good identification skills

　　Built-in spectrometer supporting second and third harmonic detection quickly and efficiently identifies semiconductor-containing devices and equipment,regardless of whether the device is powered on or off.

　　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 devices with high sensitivity,to ensure that the secret recording equipment,cell phone communication devices 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 to meet HJ/T10.2 radiation environmental protection requirements,safe and harmless to the human body.

　　Flexible and easy to operate

　　Simple and intuitive interface,fewer and more concise buttons,easy to operate manually.
