Scratch Hardness Inspection Meter

The scratch hardness tester uses a diamond indenter to move uniformly across the sample surface, measuring the minimum load required to produce a visible scratch. This instrument is used to evaluate the scratch resistance of materials such as coatings and plastics, and is applied in industries like paints, inks, and plastics for quality control purposes.
Selection
When selecting a scratch hardness tester, considerations should include a maximum load range covering testing standards, loading accuracy that meets material characteristics, adjustable scratch speed to accommodate different samples, a built-in microscope for observing scratch morphology, software capable of automatically calculating critical load, and ensuring compatibility with common substrate types.
