A Rockwell hardness meter is used to test measuring the depth of penetration of an indenter into the material under a specific load. The test begins with a minor load to the indenter and contact with the material's surface then a major load is applied to penetrate into the material. After the dwell time, the major load is released, hardness value is determined based on the depth of penetration and show the value on the hardness meter scale, Preliminary test force=98-n; Total test force=588, 980, 1471 N; Maximum height of specimens-170 mm; Range of Rockwell hardness value-HRA 20 to100 for more visit Labtron.us
