• Rockwell hardness testing machine with max sample height 250mm x 150mm depth
• Does not include indenters and test blocks
• Closed loop test force control - for a variety of hardness testing
• Automatic brake-start system begins testing when the initial force reached
• Hardness testing of plastics possible; Inside ring hardness testing

The Mitutoyo HR-530 series of Hardness Testers include a unique electronic control capable of Rockwell, Rockwell Superficial, Rockwell testing of plastics (A & B), and Light Force Brinell hardness testing. The closed loop test force control on the Mitutoyo HR-530 Rockwell and Brinell Hardness Tester allows for a wide variety of hardness testing, including plastics. The HR-530 is capable of testing the inside wall hardness of rings without cutting the ring into pieces. An easy-to-use brake-start system automatically begins testing when initial force is reached.

The Mitutoyo HR-530 Rockwell Hardness Testing Machine has Digimatic, RS-232, and USB output for data transfer. The HR-530 is available in 9.8in/250mm or HR-530L 15.5in/395mm height capacity models.

• The curved surface correction function enables curved surfaces, such as round bars and spheres, to be tested for hardness as easily as flat surfaces
• Color touch screen control panel displays statistics and graphs; up to five display formats show needed information
• The required hardness scale can be directly selected from the touch screen; the initial test force and loading force are automatically set in accordance with the selected scale, providing great convenience
• Nose-type indenter enables measurement of a specimen’s flat top surface as well as the inside surface of a cylindrical specimen
• The HR-530 is available in 9.8in/250mm or HR-530L 15.5in/395mm height capacity models
• Hardness testing of plastics according to ASTM D785 (Procedure A and B) and ISO2039-2 are also possible
• Hardness Testers are compliant with ASTM requirements
