Description

The Scratch Hardness Tester is a precision instrument used to evaluate the resistance of coatings, paints, plastics, and metals to scratching or surface damage. Designed for quality control, material testing, and research, it helps determine a material’s ability to withstand mechanical wear and abrasion under controlled force.

This tester is widely used in industrial labs, manufacturing environments, automotive, electronics, and coatings industries, offering a standardized method to assess surface hardness.
