UNI-T UT681 Series Cable Testers

The UNI-T UT681 Series Cable Testers are reliable and easy-to-use devices designed for electricians, network technicians, and field engineers who require quick and accurate cable diagnostics. With a clear LED status display, users can easily identify cable conditions, allowing fast detection of faults such as open, short, or crossover circuits. Furthermore, the tester features automatic and manual checking modes, therefore simplifying the testing process for both single and multiple cable types.

In addition, the UT681 series offers single-key operation, which makes it highly convenient for repetitive testing tasks. Moreover, it includes manual and auto power-off functionality after 10 minutes of inactivity, thus conserving battery life and enhancing efficiency. Also, a low battery indicator ensures users are always aware of power status, so tests can be completed without unexpected interruptions. Finally, the device is powered by a standard 9V battery, making it portable and ready for on-site network troubleshooting.
