Micro Ohmmeters


  • Power circuit breakers (including dead-tank circuit breakers)
  • Disconnecting switches
  • Interrupters
  • Bar installation
  • Cable splices
  • Welded joints
  • Groundings


RMO instruments are based on state of the art technology, using the most advanced switch mode technique available today. With over 15 Years in designing and  manufacturing  Micro Ohmmeters, DV Power has established wide range with  16  portable  and  3  handheld  models  of  high-precision micro  ohmmeters. The  range  includes  a  number of portable testers designed for use in tough environments, ideal for use in test facility or out in the field.  To complement the range of units we also have all the accessories you could ever need, ranging from cable clamps to remote control units.

The units are  rugged  yet  compact while maintaining  accurate low resistance  measurements. RMO generates a true (ripple free) DC current with automatically regulated test ramps. During the test RMO ramps with increasing current before measuring and decreasing current after the measurement. This approach significantly reduces magnetic transients.
