Uni-T UT685B KIT cable tester The Uni-T UT685B KIT is a multifunctional tester designed for the diagnosis, installation, and maintenance of low-voltage networks. It supports UTP, FTP, and SSTP twisted-pair cables, coaxial cables, and telephone lines, and thanks to its built-in RJ11 and RJ45 connectors and coaxial cable ports, it does not require additional adapters. The device allows for measuring cable length, locating faults, and mapping cabling to detect connection errors. The tester also offers cable location, Ethernet port testing, connection identification in 10M, 100M, and 1000M networks via the port blinking function, and PoE power detection compliant with 802.3AF/AT/BT standards. A clear 2.8" LCD screen, NCV function, input protection up to 70 V DC, automatic shutdown after approximately 10 minutes, and power supply via four AAA batteries enhance the convenience and safety of daily work.
