Metrel MicroOhm MI 3250 Low Resistance Ohmmeter

Metrel's MI 3250 is a portable, low resistance ohmmeter designed for measuring the resistance of busbar joints, motors/transformer windings, cables, fuses, aircraft frame bonds, rail and pipe bonds and lighting conductor bonding.

This low resistance ohmmeter performs directional resistance measurements from 0.1μΩ to 2000Ω with test current of up to 10A. It includes four testing modes (manual, automatic, continuous and inductive) and generates consistently reliable, accurate results when testing.

As with many of Metrel's low resistance ohmmeters, the MI 3250 comes with built-in memory storage. Up to 1000 test results can be stored in the memory, complete with timestamps, then downloaded to a PC running Metrel's included software for further analysis, reviewing and printing.

A wide variety of extra features are also included with Metrel MI 3250 - see below for a more comprehensive breakdown of this meter's capabilities.
