Mitutoyo America introduces HR-530 Series hardness testers

Feb. 3, 2018

Aurora, IL. Mitutoyo America Corp. has announced the release of the latest Rockwell hardness testers, including the HR-530 (maximum specimen size height: 250 mm; depth: 150 mm) and the HR-530L (maximum specimen size height: 395 mm; depth 150 mm). The series features an electronic control giving it capabilities for Rockwell, Superficial Rockwell, and Light Force Brinell hardness testing.

The testers can test the hardness of an inside ring wall without cutting the ring (all models). Minimum diameter is 34 mm, but inside diameters as small as 22 mm can be tested using the optional 5-mm diamond indenter.

A color touch screen displays results of statistical calculations and graphic functions, which can be stored as text data. The touch-panel display can be mounted on top of the tester to save space.

Touch-screen functions include direct hardness scale selection: The required hardness scale can be selected with the touch panel. The initial test force and loading force are automatically set in accordance with the selected scale. The testers also offer curved surface compensation and measurement: The curved-surface function enables curved surfaces, including round bars and spheres to be tested for hardness as easily as flat surfaces.

The touch screen provides statistical calculation of the maximum value, minimum value, mean value, and standard deviation when analyzing multipoint test results. It also offers numeric display of statistical analysis results, including maximum and minimum values, mean value, and graphic display of X-R control charts and histograms required for hardness evaluation. A nose-type indenter enables measurement on a flat top surface of a specimen and the inside surface of a cylindrical specimen. When testing multiple workpieces with the same height, continuous testing is possible by pressing the foot switch or the start button.
