Leeb hardness testers

Leeb hardness testers
Product is not on sale

Description

Leeb hardness testers - non destructive control devices used to measure hardness of several metals and alloys like: steel & cast steel, cold work tool steel, stainless steel alloys, gray cast irons, nodular cast iron, mergers and aluminum alloys, brass alloys / zinc brass alloys, bronze alloys, copper alloys. Leeb hardness testers are the best choice to check incoming and outgoing goods and to perfom quality control activities and maintenance of structures and works subject to wearing. Complies with standards: ASTM A965 e DIN 50156.
