Pencil Scratch Resistance Tester

The pencil scratch hardness tester determines the hardness of a coating by sliding a standard hardness pencil at a fixed angle and pressure across the surface and assessing whether a scratch is produced. It is used for quality control in industries such as coatings and plastics, with corresponding pencil hardness grades like HB-9H indicating scratch resistance.
Selection
When selecting, consider matching the hardness range of the material being tested with the pencil grade, check that the instrument's load accuracy meets standards, ensure the scratch platform is flat and stable, confirm that the operating mechanism slides smoothly, and verify that the accompanying pencils comply with graphite concentration grading specifications.
