Rockwell is often used as a “quick test” in production or in the laboratory, as well as for other processes, such as the Jominy test. The most common Rockwell method in practice is HRC. In principle, ball indenters are used for the hardness testing of softer materials and diamond indenters for testing harder materials.

ARUN Hardness Testers, Model RAS, RAB-1, RAB-250, TWIN are manually operated. All these models are suitable for testing hardness of metals sand alloys of all kinds hard or soft, whether flat, round, or irregular shape. These testers are simple in design and easy to operate, yet sensitive & accurate. Various models from the wide range are suitable for schools, laboratories, tool-rooms, inspection, heat treatment departments, factories etc.
These testers strictly confirms to IS : 1586-2000, ASTM : E 18 for Rockwell Superficial Test and IS : 2281 -2005, ASTM : E 10 for Brinell test.
