The RMO series of ducters (micro ohmmeters) are designed for low resistance contact measurement of non-inductive test objects. These ducters are based on state-of-the-art technology, using the most advanced switch mode techniques available today. RMO ducters generate a true (ripple free) DC current with automatically regulated test ramps. During testing RMO Series ducters increase current before measuring and decreasing current after the measurement. This approach significantly reduces magnetic transients.

DV Power have spent over 18 years developing and manufacturing a wide range of ducters with 16 portable and 3 handheld high-precision models available.

Applications

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

A range of 6 powerful and lightweight micro ohmmeters with current ranges up to 600 A. With single, continuous and dead tank resistance test modes the RMO-A Series are highly cost-effective micro ohmmeters.

A range of 7 powerful and lightweight micro ohmmeters with current ranges up to 800 A. For added user safety a Both-Sides-Grounded measurement mode is available alongside single, continuous and dead tank resistance test modes.

A range of 3 powerful and lightweight micro ohmmeters with current ranges up to 600 A. For added user safety a Both-Sides-Grounded measurement mode is available alongside single, continuous and dead tank resistance test modes. To decrease testing time the RMO-D series have an automatic demagnetisation feature.

A range of 3 powerful handheld battery-operated micro ohmmeters with current ranges up to 300 A. For added user safety a Both-Sides-Grounded measurement mode is available. Unlike other handheld micro ohmmeters the RMO Series offers a user selectable test current and produces a constant ripple-free current during
