The MET-U1A differs completely from traditional hardness testers. Instead of measuring the size of the indentation of the test sample using a microscope, it uses a diamond indentor mounted on a vibrating rod that presses on the test surface at a fixed load and then measures its hardness by applying ultrasonic vibrations and analyzing its damping effect. The technique is very reproducible which makes the MET-U1A a perfect tool for on-site measurements such as maintenance of large scale structures, vehicles, ships, steel towers, bridges, air planes. It is ideal for inspection of thin materials or difficult to get area such as crank shaft, gears and grooved areas.
Hardness measurements of metals and alloys on standardized hardness scales:
Rockwell (HRC), Brinell (HB), Vickers (HV) and Shore (HSD)
Three additional scales H1, H2, H3 for calibration of selfdefined hardness scales
Rm scale for determination of tensile strength
Typically suitable for components that are inaccessable for dynamic hardness testers (small articles, structures with thin walls, pipes, reservoirs, steel sheets etc.)
Leaves no visible indent on the tested article surface (crankshafts necks, mirrored surface, knives)
