Handheld Micro Ohmmeters RMO-H series

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.


✔ Advanced measurement capabilities

  • Measuring range: 0,1 μΩ – 3000 mΩ
  • Resolution: 0,1 μΩ
  • Typical accuracy: ± (0,1 % rdg + 0,1 % FS) up to 1Ω range

✔ Ideal for field & factory testing

  • Handheld, only 0,95 kg (2.1 lbs) weight
  • IP54 mechanical protection rating
  • Designed to make multiple measurements and full day’s work of testing without a battery recharge
  • Safe testing in Both Sides Grounded (BSG) conditions

Included in the standard price are the advanced DV-Win application software system which are bluetooth communication, protective transport case, ground cable and battery charger. Additional advantage, the RMO-H battery can be charged with regular car charger which is part of optional accessories.
