Description
SONEL MMR-650 MICRO OHMMETER
The MMR-650 micro ohmmeter can be used as a winding resistance meter and low resistance meter, it is designed to
measure very low resistance of both windings – including amorphous core transformers – and resistive objects. This product is made to be used in power plants, railways and maintenance companies to measure 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.
MMR-650 micro ohmmeter can be also utilized on production lines (eg. at the final production control stage).
The MMR-650 micro ohmmeter provides 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 ability to print labels to identify test items, all contribute to bringing new quality of work and allow the user to perform a wide range of measurements.
The MMR-650 micro ohmmeter is equipped with a readable colour touchscreen that, due to its 800 x 480 pixel resolution, provides both high comfort of interacting with the interface and high readability of the measurement results.
In response to the customers needs the MMR-650 micro ohmmeter has been designed to operate in difficult environmental conditions. A unique casing with the IP67 ingress protection rating ensures that the device is both waterproof and dust proof.
