The Metrel MI3252 MicroOhm is a portable low resistance ohmmeter designed to measure low contact resistance of circuit breakers, switches and busbars using a test current from 100mA to 100A.
A 4-LEAD Kelvin test method is used to eliminate test lead resistance and provide extremely accurate results that are with 0.25% of the reading with a resolution as fine as 1nanoOhm. This precise measuring system of the Metrel MI3252 MicroOhm allows the equipotential bonding and connectivity of large cross section conductors, parallel connected bars and metal stripes to be proved.
The MI 3252 can be powered from a mains supply or via an internal battery and is capable of storing up to 1000 test results which can be downloaded using supplied HVLink Pro software and imported into test reports for further analysis and distribution to clients or colleagues.
