tester and cable finder RJ45/RJ11


Network tester for comprehensive testing of network connections. Designed to test connections based on twisted-pair LAN cables, telephone cables, coaxial cables or other wired electrical connections. Especially recommended for computer networks. The set includes the main unit, probe for finding wires with a terminator.

Tax included


The set is designed to enable the measurement of all parameters necessary for network installation. The set includes the main unit, the receiver with the probe-finder and terminator. We can detect wrong connections, short circuits, interruptions. Using the probe, we can find the cable in the bundle to which we connected the transmitter by bringing the probe close together without having to connect the tester. By observing the signaling of connections, we can read their map.
