MMR-630 Micro-Ohmmeters
R82,543.00 ex vat
MMR-630 Micro-Ohmmeters - Overview

Measure motor winding resistance and other low resistances. Perform precise tests of objects of resistive and inductive nature using one instrument. This small resistance meter provides very high measurement accuracy. The measurement resolution is 0.1 µΩ. The MMR-630 model enables measurements of objects of resistive as well as inductive nature, such as transformers and motors. This is due to the large measurement current for the individual subranges and the corresponding operating modes. When testing objects of a resistive nature, rapid measurement (3 seconds) is applicable. When testing inductive objects, extended measurement is used (option of a shortened mode with a slightly lower measurement accuracy). The MMR-630 has been enhanced with special functions that allow it to be used in the production cycle for serial measurements, for example, during the inspection of large batches.

MMR-630 Micro-Ohmmeters - Features
- Measurements of objects resistive in nature:
  - welded and soldered connections, equipotential bondings, earthing conductors,
  - contacts, welds of rails, conductors and cables,
