Coating Thickness Measurement / CTM

CTMRing coating thickness

The CTM measures coating thickness on magnetic and non-magnetic base materials with high precision. It is user-friendly, sturdy and ideal for uncomplicated, reliable and non-destructive in-situ measurements

  • Ideal for condition based monitoring of piston rings in 2-stroke engines.
  • Measures non-magnetic coatings on magnetic base materials, such as chromium plated or plasma coated cast iron.
  • Also measures non-magnetic coatings on non- magnetic base materials, such as plastic coated stainless steel.
  • Automatically detects whether the base material is magnetic or non-magnetic.
  • Small enough to make reliable measurements even in hard to reach areas
