MMR-650 Micro Ohmmeter – Overview

Designed to measure very low resistances of both resistive and inductive types of objects, including amorphous core transformers. MMR-650 can be also utilised on a production line (eg. at the final production control stage). An innovative combination of a high-performance measuring device with a modern user interface and advanced data management system. Wireless data transmission, enhanced system of 2D codes and the ability to print labels to identify test items, all contribute to bringing new work quality and allow the user to perform a wide range of measurements.

This product is made to be used in power plants, railways and maintenance companies to measure the resistance of:

• windings of power transformers and motors,
• breakers, contacts,
• earthing conductors, equipotential bondings,
• welded and soldered connections,
• bolted connections,
• and other resistive and inductive objects.
