Point Contact Hardness Tester

The point contact hardness tester measures the hardness of materials by pressing a metal indenter into the surface under a fixed pressure and converting the indentation depth or diameter into a hardness value. It is used to assess the resistance of soft materials, such as coatings and plastics, to localized indentation and is suitable for rapid hardness testing of coatings and thin films.
Selection
When selecting, consider matching the material hardness range with the indenter type; soft materials should use a spherical indenter. Determine the test pressure based on the sample thickness, opting for low pressure for thin-layer materials. Ensure compliance with standard methods such as ASTM D3363, and verify the indenter size and instrument calibration cycle.
