Mitech MHR-45A Surface Rockwell Hardness Tester, based on the mechanical principle of conical diamond or hard alloy indenter pressing into the sample surface to produce indentation, realizing the material hardness measurement by measuring the depth of the indentation. According to statistics, Rockwell hardness testing is the most widely used hardness testing method in metal processing industry, which utilization ratio is more than 70%. With stable performance, easy operation, dial reading intuitive and convenient, it is widely used in metal processing and manufacturing, various metal material’s failure analysis and other fields like colleges and research institutions, and it is the sophisticated detection equipment to test the surface hardness of metal and other materials.
Function & application
Used for quality control in metal processing manufacturing
Used for failure analysis testing of metallic materials;
Demonstration experiment for education and teaching in Colleges and Universities;
Hardness testing of materials in scientific research institutions.
The surface Rockwell hardness test is based on a diamond cone or a diameter of the ball head, with a small test force to press the sample surface hardness value. In the test, the initial test force is first loaded and the main test force is loaded. After pressing the specimen test surface, the main test force is removed, and the surface Rockwell hardness value of the measured metal material can be determined,according to the depth of the specimen indentation while retaining the initial test force.
