Portable Micro-Ohmmeter with Both Sides Grounded Safety RMO-G Series

The RMO-G is a portable micro-ohmmeter designed for contact resistance measurement of non-inductive test objects and applications with increased safety requirements. It tests medium and high-voltage circuit breakers, disconnecting switches, high-current bus bar joints, cable splices, and different high-current links. Due to Both Sides Grounded and Remote Control functionalities, the instrument accurately measures even in the most demanding environments, providing additional safety to testing personnel.

A user can choose the appropriate model depending on the output current requirement, from 100 A (RMO100G) to 800 A (RMO800G). The RMO800G is the most powerful portable micro-ohmmeter on the market with an 800 A output current.

We use an unbreakable plastic case with an IP67 protective rating (with a closed lid) for the instruments’ housing. Although very portable and lightweight, RMO-G micro-ohmmeters have very high output power capabilities. High output voltage enables a wider measurement range at higher test currents. Consequently, it enables the usage of thinner/longer test cables. RMO-G generates a true DC ripple-free (less than 1 % ripple) current with automatically regulated test ramps. During the testing, it increases current before measuring and decreases current after the measurement. This significantly decreases magnetic transients and ensures great accuracy.
