Handheld Non-Linear Junction Detector
The Handheld Non-Linear Junction Detector transmits at 2.4GHz-2.5GHz with maximum power output of 0-2W EIRP in pulse mode. Receiver sensitivity operates at -140dBm or better, enabling superior detection of semiconductor components. The device receives harmonics at 4.8GHz-5.0GHz and 7.2GHz-7.5GHz (second and third harmonics). Detection distance reaches 10 meters or greater, compliant with C-level standards per GA1236-2015. The compact handheld design measures 227mm by 112mm by 70mm with device weight at 0.5kg or less. Total package weight including accessories reaches 2.7kg. Package dimensions are 304mm by 228mm by 114mm (±10mm). The internal lithium battery provides continuous operation exceeding 4 hours. IP65 protection rating ensures dust-tight and water-resistant construction during field operations.
This NLJD penetrates 550mm thick brick walls, meeting C-level penetration standards specified in GA1236-2015. Operating temperature range spans -30°C to +55°C, supporting deployment in diverse climate conditions. The device detects all semiconductor components including SIM cards, mobile phones, listening devices, covert cameras, and voice recorders—whether powered on, in standby mode, or completely switched off. Audio alerts transmit through an internal speaker or connected earphones. Visual display indicates detected material type as either silicon or metal, eliminating false positives from corroded metals and oxidized surfaces.
The Handheld Non-Linear Junction Detector deploys at corporate offices, government facilities, VIP residences, and security checkpoints to detect concealed electronic surveillance devices. Embassy personnel conduct counter-intelligence sweeps of sensitive areas. Correctional facility staff inspect visitor belongings and inmate areas for smuggled communications devices. Border security teams screen luggage and personal items at international checkpoints for prohibited electronics.
Tactical Supply Pakistan provides the Handheld NLJD with proven reliability for professional counter-surveillance applications. The brand delivers advanced semiconductor detection technology with intuitive operation and dedicated technical support.
