Loop Impedance Testers

Loop impedance measures the total resistance to electrical current in a closed circuit. It’s measured in ohms and plays a key role in electrical safety. Using a tester to carry out an earth loop impedance test confirms the system can respond correctly in the event of an earth fault.

Our range of loop impedance testers is designed to give accurate, reliable readings. By keeping fault loop impedance within safe limits, you can meet safety standards and ensure your electrical installations work as they should.
