Be confident in your purchase, we're an Authorized PCE Instruments Dealer. Highlights: For use with cast steel, hammered steel, cold-rolled steel, stainless steel, cast iron, ductile iron, aluminum alloy, brass, bronze and forged copper alloy metals The PCE 950 Electronic Metal Hardness Tester is used to determine the hardness of 10 different types of metal (i.e., cast steel, hammered steel, cold-rolled steel, stainless steel, cast iron, ductile iron, aluminum alloy, brass, bronze and forged copper alloy) according to the Leeb rebound method. In addition to Leeb hardness units (HL), the metal hardness tester displays hardness measurements in Rockwell C, Rockwell B, Rockwell A, Brinell, Vickers and Shore hardness units. In this dynamic hardness testing method, a small carbide ball hits the test surface. The quotient of rebound and impact velocity is directly related to the material hardness and can be converted into different hardness scales (i.e., HRC, HRB, HRA, HB, HV and HS). Thanks to the measuring instrument's compact pocket-sized ergonomic design and integrated impact device, hardness tests can be performed quickly and easily in the field and on the manufacturing production floor. An internal memory offers storage for up to 600 readings, and the included PC-compatible software and USB cable allow for simple and efficient data transfer to a computer for documentation and analysis of hardness test results. Ideal for the incoming and outgoing inspection of metal parts and components, the PCE-950 hardness tester is an essential tool for machinists and manufacturing quality control and assurance professionals.
