The Ermenrich NetGeeks NL70 Cable Length Tester is a multifunctional measuring tool for testing various network cables (categories 5E/6E) telephone coaxial cables and common wires. The device is used for testing cables up to 1 000 meters (3 280ft) long. The kit includes 8 remote units allowing for 8 simultaneous measurements.

With the Ermenrich NetGeeks NL70 you can test cables for open circuits and short circuits as well as crossed reversed and split pairs. The cable length tester can measure the distance to the open circuit. There is a cable trace function to locate the target cable in the cable bundle. The Port Flash feature enables you to find the exact port on the network switch or router to which the target cable is connected. With this tester you can perform a PoE test and PING test and save data to a memory card.

The Ermenrich NetGeeks NL70 provides high measurement accuracy and can be calibrated if needed. The transmitter and receiver are powered by rechargeable batteries so you won’t have to buy and replace batteries often. A single charge provides 20 hours of transmitter operation and 50 hours of receiver operation.
