Resistance Meters

In various applications it is of great importance to accurately measure resistance.

This can be very high resistance (Mohm or even Gohm), but also very small resistors (milliohm and micro ohm).

For each application there is a specific measuring device.


  • Engines and generators
  • Transformers
  • Grounding electrical devices
  • Grounding electrical networks
  • Contact resistance in switches and disconnectors
