Linear Five-Finger Scratch Tester

The five-finger scratch tester simulates daily wear by repeatedly scratching the sample surface with five metal fingers under different loads. It is used to evaluate the scratch resistance of materials such as coatings and plastics, and is applied in quality control of surface coatings for automotive interiors, appliance casings, and more.
Selection
When selecting, consider the load range and scraper material required by the test standards to match the actual usage scenarios of the material. Confirm the instrument's stroke accuracy and speed control capabilities, and examine the adaptability of the sample fixtures. Pay attention to the data recording methods and the convenience of equipment maintenance.
