Ohm Meter

We offer a complete product range of Micro Ohm Meter

Micro Ohm Meter

The Micro Ohmmeters – RMO series instruments are designed for contact resistance measurement of non-inductive test objects. RMO instruments are based on state of the art technology, using the most advanced switch mode technique available today. 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 eliminates magnetic transients.
With over 15 Years in designing and manufacturing Micro Ohmmeters, DV Power has established wide range with 18 models of high-precision micro ohmmeters.

Applications :

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