HR-150A Rockwell Hardness Tester
Overview
The HR-150A Rockwell hardness tester measures hardness for hard metals, carburized/quenched steels,
hard cast irons, mild steels, and Al/Cu alloys. It follows the Rockwell principle per ISO 6508
and ASTM E18: the hardness value is derived from the depth difference between the preliminary
and total test forces. Typical users include QC departments, universities/colleges, research labs, and industrial laboratories.
