Compact Nonlinear Junction Detector
The Compact Nonlinear Junction Detector is an portable, high-sensitivity device designed for detecting hidden electronic circuits within walls, furniture, ceilings, and containers. Operating on a 2400MHz band, it features a built-in lithium battery and a powerful harmonic detection system. Despite its reduced size, it supports second and third harmonic analysis, ensuring strong recognition of semiconductor elements in various environments. Its pulse mode transmission reaches up to 1W (EIRP), maintaining reception sensitivity levels as low as ≤ -125dBm.
This compact unit is built for stealth and practicality, weighing just 0.52 kg. With a detection range beyond 6 meters and the ability to penetrate 370mm of brick wall, it delivers reliable performance in field conditions. Its energy-saving design includes automatic shutdown when idle, and it features a clear LCD interface with sound, vibration, and visual prompts for alerts. The operating temperature range spans from -20°C to 55°C, and the device functions reliably under humid conditions up to 93% RH without condensation.
The Compact Nonlinear Junction Detector is widely used in environments requiring strict surveillance countermeasures—military, intelligence, correctional institutions, and VIP privacy protection. It quickly identifies threats such as concealed mobile devices or unauthorized audio/video recorders, even when the electronics are turned off or dormant.
Backed by Tactical Supply Pakistan, this model combines robust detection performance with flexible operation in sensitive field missions. Its intuitive controls and reliable alert systems make it an essential asset in high-security operations.
Is this detector suitable for high-humidity environments?
Yes, it functions effectively in environments with up to 93% relative humidity, provided there is no condensation present.
