    Detailed Product Description
    Initial Test Force: 98N (10kgf) Loading Type: Manual
    Test Force: 60, 100, 150kgf Rockwell Scale: HRA, HRB, HRC

    Bench Top Manual Rockwell hardness Tester with manual rockwell hardness test procedure


    Main application:
    Hardened steel, quenched and tempered steel, annealing steel, bearing steel, strip steel, hardened steel sheet, hard alloy, etc.

     

    Working principle of Rockwell hardness test:

    The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload. There are different scales, denoted by a single letter, that use different loads or indenters. The result is a dimensionless number noted as HRA, where A is the scale letter.

    Features:

    1. The dial will display hardness value directly, indicator responses sensitively, show the hardness value accurately, the test value is more accurate than national standard;
    2. One-time casted molding shell, stable structure and it is not easy to be out of shape. It can work under harsh environment; the shell coating adopted car paint technology with white color. it has strong scratch resistance capability and still look bright as new after use many years;
