Description Technical Info Reviews Accessories

Metrel's MI3252 is a portable low resistance ohmmeter ideal for finding low contact resistances on high, middle and low voltage circuit breakers & disconnecting switches, cable splices, high current busbar joints, welding joints and more.

Built inside its own carrying case for easy transportation, the Metrel MI3252 is designed for on-site use, providing technicians with all the facilities they need for testing resistances to 20Ω with adjustable testing current from 100mA to 100A. The case is protected to IP64 and is rugged and lightweight.

The Metrel MI3252 ohmmeter is a downloadable unit with built-in memory storage. Up to 1000 test results can be stored directly on the instrument, then downloaded to a PC using RS232 or USB connection (and Metrel's software) for further analysis.

Additional features of this unit include voltage drop measurements, on-screen resistance bargraph indication and the ability to set custom limits for your tests (plus PAS/FAIL evaluation).
