A Rockwell hardness meter (motorized type) involves the automated application of test forces and measurement of the indentation depth to determine the hardness of a material.  the indenter movement is automated. The hardness value is automatically determined based on the depth of penetration. Preliminary test force=98-n; Total test force=588-980-1471-n; Brinell hardness test=306-613-1839-n; Vickers hardness test=294-588-980-n; Magnification of Microscope=37-575-x;Maximum height of specimens-180 mm; for more visit Labtron.us
