A Hardness Testing Machine is an instrument used to measure the hardness of materials, primarily metals, plastics, and composites. Hardness is a material’s resistance to deformation, particularly permanent indentation or scratching. These machines are vital in manufacturing, quality control, and material research to ensure material properties meet required standards.
