Kyoritsu 4118A Loop Impedance Meter


(Excl. GST)


A custom microprocessor controlled loop impedance tester from the world class manufacturer, Kyoritsu.

Where the loop resistance of an earth circuit is too high, in the event of an overload or short circuit, it's possible that that circuit breakers or earth leakage devices might become inoperative. To prevent such accidents, the earth circuit resistance must be measured to ensure it is sufficiently low.
