100A MicroOhm Meter MI 3252 – Metrel

Metrel’s 100A MicroOhm Meter is a portable low resistance ohmmeter used to measure low contact resistances of circuit breakers, switches and busbar joints using test current from 100 mA to 100 A. Used 4-lead Kelvin testing method ensures very high accuracy of results (0.25%) due to elimination of test leads resistance. The instrument can be powered from both mains supply and internal battery. PC SW HVLink PRO supplied as a standard accessory enables downloading, analysis and export of test results and printing of test reports.
