Lightweight High Current Micro-Ohmmeters

The RMO-200G series micro-ohmmeters are the standard for many USA power utilities, offering a lightweight design and 200A current capability. These devices use a TRUE DC power source to provide ripple-free outputs, preventing false trips of breaker CT controls. The new RMO-H handheld high current micro-ohmmeter is ideal for use in bucket trucks and features a long-lasting Li-Po battery for all-day operation.

  • Standard Model: RMO-200G with 200A capability and lightweight design.
  • Handheld Model: RMO-H with a Li-Po battery for extended use.
