UNI-T UT685B KIT TDR Cable Tester

is a professional-grade Time Domain Reflectometer (TDR) designed for accurate cable fault location and length measurement. It provides a fast and precise way to detect open circuits, short circuits, and other impedance-related faults in a wide range of metallic cables such as coaxial, twisted-pair, and network cables. With its advanced TDR technology, it enables technicians and engineers to identify cable issues quickly, minimizing downtime and maintenance costs.

The UNI-T UT685B KIT TDR Cable Tester supports both single and dual-channel testing modes, offering exceptional accuracy and versatility. It uses high-speed signal reflection analysis to determine the exact distance to a fault, ensuring reliable performance even over long cable lengths. Moreover, it can measure cable lengths up to several kilometers, depending on the cable type and velocity factor.

In addition, the device features a user-friendly interface with a bright LCD display that provides clear readings of test parameters, fault locations, and cable length results. Its portable design, lightweight build, and rechargeable battery make it convenient for field use. The tester is also equipped with built-in memory for data storage, allowing users to review or export results later.

Furthermore, the UNI-T UT685B KIT includes all essential accessories such as test leads, adapters, and carrying case, making it ready to use straight out of the box. It is ideal for network maintenance, telecommunication systems, CCTV installations, and electrical wiring inspections.
