Price Match Guarantee & Advice

Sonel's MMR-630 is the upgraded version of the Sonel MMR-620 with enhanced resolution.

A portable solution for measuring low resistance levels in many different applications, Sonel's MMR-620 includes multiple measurement modes, easy-to-configure testing procedures and delivers consistent, accurate results with low resolution.

The following measurement modes are available on the Sonel MMR-630 low resistance ohmmeter:

  • Normal Mode - standard insulation resistance test
  • Automatic Mode - as the test leads are connected to the object, the MMR-620 will automatically start the measurement with dual direction current flow and average result display
  • Continuous Mode - every 3 seconds for resistive objects or continuous measurement on inductive objects
  • Window Mode - set an upper/lower limit with display of average measurement result

All measurement results can be stored directly in the MMR-630's internal memory, with support for download to PC (requires Sonel's optional software package).
