Scratch Hardness Gauge

The scratch tester uses a diamond indenter to glide uniformly across the coating surface while gradually increasing the load, detecting the critical load value at which the coating peels off. It is used to evaluate coating adhesion and wear resistance, commonly applied in quality testing for automotive paints and plastic coatings.
Selection
When selecting a scratch tester, consider matching the coating hardness range with the instrument’s load capacity, ensure the scratch speed is adjustable, check sensor accuracy and data recording functions, choose fixtures based on sample dimensions, and verify instrument compatibility by referring to industry standards.
