For Accurate Ductor Testing – Raytech Micro Centurion II Micro-Ohm Meter

Raytech Micro Centurion II MC2 200A Precision Micro Ohm MeterA contact resistance test (also known as a ductor test) measures the resistance of electrical connections such as joints, terminations and connectors. These can be connections between any two conductors, for instance busbar sections or cable connections. The test measures the resistance at the micro- or milli-ohm level and is used primarily to verify that electrical connections are made properly, and can detect the following problems:

  •                  Loose connections
  •                  Adequate tension on bolted joints
  •                  Eroded contact surfaces
  •                  Contaminated or corroded contacts
