The Rockwell hardness testers manufactured by XZBELEC company apply Rockwell hardness testing principle, with initial test force 10kgf, total test force 60kgf, 100kgf and 150kgf, and two common kinds of indenters:
120° diamond cone indenter
1.588mm carbide alloy indenter
The superficial Rockwell hardness tester has different test force of 3kgf initial test force and total force 15kgf, 30kgf, and 45kgf. Users could choose different Rockwell test force and indenter according to different kinds of material, hardness and thickness. The resolution of Rockwell hardness testers can be 0.5 HR, and the resolution of the patent product digital magnetic Rockwell hardness tester can be as precise as 0.1 HR.
