Latest portable hardness tester technology. Utilizes both ultrasonic and dynamic type portable hardness testers in one unit. Can test non-destructive and handle small or thin work parts down to 2mm of thickness, as well as testing large parts. Extremely versatile, with many options and configurations to handle all types of hardness tester applications.

“Ultrasonic Contact Impedance” is based on a 136 degree diamond at the end of a vibrating rod being depressed into the test surface at a fixed load. The difference in Ultrasonic vibration frequency is then calculated into a hardness value. The UCI hardness test procedure is slower than the Dynamic Impact style, however the “UCI” method of hardness testing is portable, easy and accurate. It also has its own advantages when utilized for certain hardness testing applications. UCI hardness testers are not restricted to large mass items like dynamic type testers. These hardness testers can test metals as thin as 2mm and at a hardness value as low as 20HRC (75HB). They also excel at performing hardness tests on larger, harder metals as well. Another reason for the rise in popularity is due to the fact that the UCI method is categorized as “Non-Destructive”. That translates into less scrap parts/ lower mfg costs due to necessary inspections.

“Dynamic Impact” is based on the Leeb principle of hardness developed by Dietmar Leeb in the 1970’s. A spring loaded impact body is thrust to the test surface, effecting rebound. The speed of both the initial thrust and the rebound is measured in a non-contact mode. This is calculated as a Leeb hardness value and then automatically converted to Rockwell C, B, Brinell, Vickers and Shore hardness Values. It has effectually brought easy, fast and accurate results to portable hardness testing.
