About МЕТ-U1А ULTRASONIC Portable Hardness Tester

Description The hardness tester is a portable device consisting of an electronic module and a probe connected by a cable. The electronic module is located in an aluminum dust-proof-and-moisture-proof body of IP 66 protection index. Hardness tester MET-U1A is equipped with an ultrasonic probe U15 with the load of 1,5 kgf (14.7N). Operates according to UCI - ultrasonic contact impedance method (ASTM A 1038, DIN 50159). UCI-method enables to control the hardness of metal and alloy items of any weight and dimensions, but is mostly suitable for measurements on the surface of thin and light articles with homogeneous structure that cannot be measured using the dynamic rebound method (Leeb). Measurement of metal and alloy hardness according to standardized hardness scales: Rockwell (HRC), Brinell (HB), Vickers (HV) and Shore (HSD); Availability of three additional scales H1, H2, H3 for calibration of various hardness scales (for example, Rockwell B, Super-Rockwell, Brinell (HBW), etc.) for hardness control of steel and other metals (for example, aluminum alloys, copper, etc.); Use of Rm (MPa) scale for determination of tensile strength (for pearlitic class steels); Possibility of hardness control of items that are inaccessible for stationary hardness testers due to their dimensions; Hardness measurements of articles of any mass and thickness starting from 1 mm, inaccessible for dynamic portable hardness testers (metal coatings, small parts, thin-walled structures, pipes, reservoirs, steel sheets, etc.); Does not leave any visible indent on the tested article surface (crankshafts necks, mirror surfaces, knives); Availability of archive and software for PC connection. Calibration of hardness testers is carried out at the completion of hardness testers production.
