More Information

Overview

TOhm Meter 5478 is a digital multipurpose tester intended for testing, analyzing, inspecting and maintaining high voltage insulation. The instrument offers a complete set of functions to measure and detect effectively all parts of current in an insulation system.The instrument can supply an output power of 5 W and a test voltage of up to 5000 V and therefore is capable of resistance measuring up to 5 TOhm.
