UNI-T UT681L Network Cable Tester

The UNI-T UT681L tester is a simple but effective tool for quick diagnosis of network and telephone cables. With it, you can easily check the continuity of cables, detect short circuits, crossed pairs and circuit breaks. Its compact form, convenient one-button operation and clear LED system make the UT681L ideal for the daily work of network technicians, installers or service technicians.

The most important functions in one device

The UT681L supports testing cables terminated with RJ45 and RJ11 connectors, allowing you to quickly verify connections on Ethernet networks and telephone lines. The LEDs (LED1~LED8 and LED_G) indicate the status of individual cables, allowing you to detect faults such as breaks, shorts or cross-connections. Two modes - fast and slow - are available, allowing you to tailor the test to your specific application.

Always ready for work

The device is powered by a standard 9V battery, ensuring mobility and quick start-up without the need for charging. An automatic power-off function after 10 minutes of inactivity extends battery life, while a low-battery indicator reminds you to replace the battery. Thanks to its compact size and low weight, the UT681L fits easily in any service bag.

Durability and reliability in every situation

The robust, red-grey housing ensures durability when operating in a variety of conditions. The controller is designed to operate in a temperature range of 0 to 40°C and in humidity up to 80%, making it ideal for both office and field use. The product is CE and UKCA certified, confirming its safety and compliance with European standards.
