The method used by UCI to measure hardness complies with ASTM A1038. The ultrasonic contact impedance (UCI) probe’s intended use is for hardness testing in areas with a thin thickness (starting from 1 mm). It is explicitly made for assessing the hardness of surface-hardened layers and objects with complex surface shapes.

This technique is quick and straightforward: place the probe on the surface of the object being tested, apply the necessary pressure, and save the hardness value that appears on the device’s display. All objects thicker than 1 mm can have their hardness value measured using a small diamond indenter. The hardness tester with the UCI probe leaves far smaller prints (imprints) than the majority of bench hardness testers would, making the UCI method of hardness testing the least harmful. The ideal option is a portable hardness tester with a UCI probe. Portable UCI Hardness Tester comes with a CE certificate of compliance.
