JHR-150MT Manual Twin Rockwell Hardness Tester
Brief Introductions:
Introductions:
JHR-150MT Manual Twin Rockwell hardness tester (commonly known as dual Rockwell) has novel and beautiful appearance, which combines the functions of common Rockwell and surface Rockwell hardness tester in one machine, this expands the scope of application, and is a full-Rockwell hardness tester. It is easy to change initial test force and hommization operation .This hardness tester has good reliability and intuitiveness.
The hardness tester for hard alloy, carbide, the surface of hardened steel, hardened sheet steel, hardened steel, quenched and tempered steel, chilled cast iron, cast iron, aluminum, copper, magnesium alloy.
