Overview

First handheld micro ohmmeter (only 0,95 kg / 2.1 lbs) which generates regulated DC current up to 300 A!

The RMO-H micro ohmmeters are ideal for a number of applications for contact resistance measurements of non-inductive test objects. Typical applications are testing a circuit breakers and disconnecting switches, high-current bus bar joints, cable splices, welding joints, etc.

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.
