Analogue Rockwell Hardness Testers are hardness scale based on indentation hardness of a material. The Rockwell test measuring the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). There are different scales, denoted by a single letter, that use different loads or indenters. The offered Analogue Rockwell Hardness Testers are built to sit atop a work bench and test sample blocks. They are very efficient
