The RMO-H Series contains the first ever handheld micro ohmmeter which generates user selectable regulated DC current up to 300 A. This series is ideal for numerous applications of contact resistance measurement of non-inductive objects, such as circuit breakers and disconnecting switches, high-current bus bar joints, cable splices and welding joints. All measurements are time and date stamped and can be analysed using proprietary DV-Win software.

DV Power provides a 3-year warranty on all test instrumentation. This is a guarantee to our customers that they will receive the highest quality test equipment on the market.

RMO-H series consists of three models:

  •    RMO-H1 (up to 100 A DC)
  •    RMO-H2 (up to 220 A DC)
  •    RMO-H3 (up to 300 A DC)

Regulated, user selectable test current


 RMO-H3 generates up to 300 A DC (ripple-free) test current, user selectable, generated in an automatic   regulated test ramp. This revolution in handheld micro ohmmeters technology is enabled by use of Li-Po   batteries.
