Cable testers for everyone is the motto of CableJoG Ltd. They design, produce and distribute a range of cable testers. An overview:

All of these cable testers have at least one memory option that allows for quick testing of similar cables. CablejoG cable testers check for continuity. The minimum resistance detected varies from model to model, but is always sufficient to test an entire roll or cable reel. The AudioJoG cable testers are designed for the Audio Professional who needs to check various audio cables. Using two AudioJoG cable testers it is possible to test the cable in situations without bringing the cable ends together into one unit. Testing is performed from the local end, but results can be seen on both sides.
