ROCKWELL RB-1A/HT

ROCKWELL RB-1A/HT is an analog hardness tester that measures the hardness of metallic materials by the Rockwell C, B, A method according to the standard STN EN ISO 6508.

The hardness value is evaluated after the hardness test directly and separately for each measuring method. Using a diamond indenter, the value is read from scale C and using the ball from scale B.
