UNI-T UT 685B KIT TDR Cable Tester

UT685B KIT can test various types of cables (including twisted pair cable, coaxial cable, and POE network cable): you can find the cable, detect the cable length, and line sequence, and confirm whether it is POE and POE standards. Plus, it integrated RJ11, RJ45, and coax test ports to support virtually any low-voltage cable testing without needing awkward adapters.

Effectively reduce the operator’s ineffective testing and improve work efficiency, which makes high-quality installations more efficient and easier to troubleshoot.

Description
Brand

The UNI-T UT685B Cable Tester is a professional TDR (Time Domain Reflectometry) tool designed for accurate cable testing, fault detection, and network troubleshooting. It supports multiple cable types, including twisted pair, coaxial, and POE network cables, so users can perform a wide range of testing tasks with a single device. Moreover, it helps locate cables, measure cable length, and identify wiring sequences with high precision.

In addition, the device features advanced TDR technology, which allows users to detect faults without blind spots. It can measure cable lengths from 2.5m up to 500m with high accuracy, therefore making it suitable for both short and long cable installations. As a result, technicians can quickly identify issues such as breaks, short circuits, and incorrect wiring.

The UNI-T UT685B Cable Tester also includes integrated RJ11, RJ45, and coaxial ports, eliminating the need for extra adapters. Furthermore, it supports POE detection and identifies POE standards such as 802.3AF, AT, and BT, which means users can test network power systems efficiently.
