Clamp testers are unique in that they include a current clamp on their end that allows you to measure the properties of an electric current without making physical contact with the wire or disconnecting it. Test for current, voltage, resistance, continuity, frequency and more. We even have options that test for ground resistance and leakage. Our selection includes testers from trusted brands including Greenlee, Klein Tools, Triplett and more.
