Time Domain Reflectometry (TDR) Cable Length Meter

Klein Tools' cable length meter is a portable time domain reflectometry (TDR) cable length tester. It measures cable length, calibrates velocity of propagation (VoP) values, finds the distance to faults in cables, and provides built-in tone generation for cable tracing. This tester offers accurate cable length measurements for various cable types at an affordable price. The package includes test leads and a carrying case.
