UNI-T UT681L network cable tester

UNI-T UT681L network cable tester
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 breaks in the circuit. Its compact form, convenient one-button operation and clear LED system make the UT681L perfect for the daily work of network technicians, installers or service technicians.


The most important functions in one device
UT681L supports testing of cables terminated with RJ45 and RJ11 connectors, allowing quick verification of connections in Ethernet networks and telephone lines. LEDs (LED1~LED8 and LED_G) show the status of individual cables, allowing you to detect errors such as breaks, short circuits or crossings. Two modes are available - fast and slow - allowing you to tailor the test to your specific application.


Always ready to work
The device is powered by a standard 9V battery, ensuring mobility and quick startup without the need for charging. An automatic shut-off function after 10 minutes of inactivity extends battery life, and a low-charge indicator reminds you to replace the battery. Thanks to its compact size and low weight, the UT681L will easily fit into any service bag.


Durability and reliability in any situation
The rugged, red-gray housing ensures durability during operation in various conditions. The tester is designed to operate in a temperature range of 0 to 40°C and 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.
