DV-Power RMO-Hxx Series Micro Ohmeter

The RMO-H is battery operated and handheld micro-ohmmeter. It is designed for a variety of applications for contact resistance measurement of non-inductive test objects. Typical applications are accurate testing of:

  • medium and high-voltage circuit breakers,
  • disconnecting switches,
  • high-current bus bar joints,
  • cable splices,
  • and different high-current links.

Even more, it accurately measures in high-induction filed environments and substations, as well as in factory testing.

RMO-H Series contains six models in total, divided in 2 sub-series depending on the test leads length requirement and the battery type:

  • RMO-H1, RMO-H2 and RMO-H3 models are intended for use with short cables (e.g. 1,3 m / 3 m / 5 m). The 1-cell Li-Po battery with 8200 mAh capacity provides output voltage up to 4,1 V DC.
  • RMO-H21, RMO-H22 and RMO-H23 models are ideal for applications where test leads with lengths > 5 m are required.  The high output voltage (up to 8,3 V DC) is provided by 2-cells 5600 mAh Li-Po battery.
