Hardness testers are instruments specifically designed to detect the hardness of materials. To make a measurement of the hardness of a material, the durometer should do penetration, leaving an imprint on the point tested (called a witness).
Non-destructive control device used to measure the elastic properties of several metals and alloys., the Leeb Hardness Testers are the best choice to recognize raw goods sent by suppliers, quality control in the production line and maintenance of structures and works subject to wearing.
