UNI-T UT685B KIT TDR Cable Tester

The UNI-T UT685B KIT is a compact, handheld Time-Domain Reflectometer (TDR) cable tester, meticulously tailored for diagnosing copper cabling such as CAT 5E, CAT 6, CAT 6A, and CAT 8 twisted-pair lines, as well as coaxial cables. Its design emphasizes swift identification of wiring conditions showing wiretaps, open/short circuit locations, split pairs, and cable length all at a glance on a graphical LCD. When paired with the UT683R receiver, it also provides both optical and audio guidance for locating cable runs. This kit stands out with its support for Power over Ethernet (PoE) diagnostics, capable of sensing whether a cable carries PoE and identifying the specific standard—802.3af, 802.3at, or 802.3bt. It includes integrated ports for RJ45, RJ11, and coax connectors, simplifying testing across multiple cable types without extra adapters. Its TDR technology ensures no “blind spots” during testing and aids in accurately estimating fault distances. Designed for field technicians and network engineers, the UNI-T UT685B KIT combines precision with ease of use. A backlit 2.8″ LCD with a graphical interface ensures screen readability even in low-light environments. Built-in protections such as 70 V DC input protection and automatic power-off enhance safety and power management. Its rugged portability is further emphasized by a carry pouch and battery operation, making multilevel cable diagnostics both faster and more efficient.
