Hardness Tester

A hardness tester is a device that measures a material's resistance to permanent deformation by applying a standardized force through a specially shaped indenter. The hardness is determined by the size or depth of the indentation created, with different types of hardness testers (e.g., Rockwell, Brinell, Vickers) using different indenters and methods to measure the resulting impression. These testers are used in quality control for materials such as metals, plastics, and ceramics across various industries.
