Mechanical Scratch Tester

The mechanical scratch tester assesses coating adhesion by moving a fixed-load stylus across the sample surface at a constant speed, evaluating based on scratch depth or visible damage. It is used to detect the scratch resistance of materials such as coatings and plastics, ensuring that the surface durability of products meets usage requirements.
Selection
When selecting, consider the sample material and thickness to match the load range and stylus type; confirm the instrument's accuracy and speed control according to testing standards; check whether the data recording method meets requirements, while balancing ease of operation and maintenance costs.
