RMO-H Series (Rental) - DV Power Handheld Micro Ohmmeters

This is a rental unit. Prices showing are for a 2-week rental. 

The RMO-H is a battery-operated 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 field environments and substations, as well as in factory testing.

RMO-H Series contains six models in total, divided into 2 sub-series depending on the test lead 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 an output voltage of 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-cell 4100 mAh Li-Po battery.

The test current is regulated and can be selected in a range of 1 A to a maximum of 300 A, depending on the maximum test current rating:

• RMO-H1, RMO-H21 models – up to 100 A DC
• RMO-H2, RMO-H22 models – up to 220 A DC
• RMO-H3, RMO-H23 models – up to 300 A DC.

Unlike many other handheld micro-ohmmeters available on the market, our instruments have regulated and user-selectable test currents. Therefore, RMO-H instruments generate an automatically regulated test ramp with stable and ripple-free current during measurement. These revolutionary characteristics in handheld micro-ohmmeters technology are possible by using sophisticated Li-Po batteries. Consequently, modern battery technology enables you to do multiple measurements, and a full day of testing without recharging the battery.

With all RMO-H models, it is possible to make tests on Both Sides Grounded testing objects, in an increased safety environment. Finally, these features in combination with a user-friendly interface (1-click to measure) significantly speed up the testing procedure and make it safer.

These instruments store up to 1000 measurements on the internal micro SD card.

Our free DV Win software communicates with the RMO-H micro-ohmmeters via a wireless Bluetooth interface. Furthermore, it allows you to download test results, analyze them, and generate fully configurable test reports.
