Digital Network Cable Tester Wire Tracker with POE Detection, Continuity & Short Circuit Test for RJ45 8P Ethernet Cable and RJ11 4P Telephone Line, Multi-Function Line Finder for Wiring Inspection

This professional multi-functional cable tester is an essential tool for network engineers, electricians and IT maintenance personnel. It combines wire tracing, continuity testing and POE power detection in one compact device, covering daily wiring inspection requirements for Ethernet and telephone systems.

It precisely tests RJ45 8-core CAT5/CAT6 network cables and RJ11 4-core telephone lines, quickly identifying open circuits, short circuits, miswires and cross-line faults through accurate continuity analysis. The built-in POE test module safely detects voltage status of POE power supply lines, effectively avoiding equipment burnout during IP camera and POE switch installation.

The wire tracker transmitter sends out specific frequency signals, while the receiver pinpoints target cables among tangled wire clusters, wall embedded lines and trunking wiring with adjustable sensitivity for strong anti-interference performance. Equipped with intuitive digital reading screen and loud audible alert, the operation is straightforward for both novice and professional technicians.

Powered by common batteries with ultra-low standby power, the durable handheld structure is portable for on-site construction, office network renovation, monitoring system wiring and residential telephone line troubleshooting projects.
