hardness tester

A hardness tester is a device used to measure how resistant a material is to deformation, particularly permanent indentation. It assesses the strength and durability of materials like metals, plastics, and ceramics by applying a specific force to a hard object, such as a ball or diamond, and measuring how deep it penetrates the surface. The results help determine material suitability for various applications, ensuring safety and reliability in industries like manufacturing, construction, and engineering. Different testing methods exist, including Rockwell, Brinell, and Vickers, each suited for different materials and thicknesses.
