MEASURING METHOD: UCI & Leeb Portable Hardness Testers

There are two basic methods of portable hardness testing that are accepted in the field today. 

"Ultrasonic Contact Impedance" testing 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 portable hardness tester 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 testing applications. 

UCI portable hardness testers are not restricted to large mass items like dynamic type testers. These portable 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 fewer scrap parts and lower manufacturing costs due to necessary inspections. 

"Dynamic Impact" is based on the Leeb principle of portable 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 that automatically converts to Rockwell C, B, Brinell, Vickers and Shore Values. It has effectually brought easy, fast and accurate results to portable hardness testing.

With the 6000 Series, the user selects the model to match the instrument to the range of applications and whether the requirement is for a manual or motorized probe.  Manual probes are best fo 1 to 10kg and motorized are recommended for .3 to 1kg and smooth machined surfaces.
