Network Cable Tester & Wire Tracker Tool for RJ45/RJ11, LAN & Telephone Line Finder, Continuity & DC Test, LED Flashlight, Earphone Support

Expert Features Fast and Accurate Wire TracingThis professional network cable tester and wire tracker is designed to quickly locate telephone lines, LAN cables, and metal wires within complex cable bundles. It allows technicians to identify target cables on patch panels, switches, routers, and wall outlets without confusion or guesswork. Multi-Function Cable Testing CapabilityThe device supports comprehensive LAN cable condition verification, including continuity testing, open circuit detection, short circuit identification, and cross-wire analysis. It evaluates Cat5, Cat5e, and Cat6 UTP/STP network cables with high accuracy. Auto Scan and Wire Sequence CollationThe auto-scan mode rapidly tests double-twisted cables across all eight core wires plus grounding. Based on 16 wire sequence combinations, the tester can clearly determine wiring errors such as breaks, shorts, miswires, and crossed connections. Telephone and Electrical Line DetectionBeyond network cables, this tool traces RJ11 telephone lines and detects electrical wires in systems without the need for drilling or dismantling, making it ideal for maintenance and troubleshooting tasks. Adjustable Signal Speed, Frequency, and VolumeBuilt-in speed and frequency regulation allows precise control during testing and tracing. A volume adjustment knob helps optimize sound levels, especially when working in quiet or noisy environments. Noise-Resistant Professional DesignThe included earphone enables accurate signal detection in high-noise areas such as server rooms and industrial sites. The probe supports direct contact on bare lines while maintaining safe operation. Integrated LED Flashlight and Power-Saving FunctionsA bright white LED flashlight assists testing in dark or low-light areas. The inching switch supports automatic power-off delay for energy saving, while low-battery indication ensures uninterrupted work. Built for Field ProfessionalsWith strong anti-jamming capability, long-distance signal transmission up to 3 km, and ergonomic handheld design, this tester is ideal for telecom engineers, network technicians, power supply teams, IT maintenance staff, and infrastructure installers.
