    Key performance parameters

    · Preload: 98.1N(10kgf)

    · Total test force: 588.4N(60kgf),980.7N(100kgf),1471N(150kgf),


    · Conversions: digital Rockwell hardness tester can convert the measured Rockwell hardness value to

    other scales or even tensile strength. Example: the value of HRA scale can be automatically converted into

    HBS, HBW, HV and HK value; Convert the value of HRB scale into HB10, HB30, HV, HLD, σb and HK value;

    Convert the value of HRC scale into HBS, HBW, HV, HLD, HR15N, HR30N, σb and HK value; Convert the

    value of HRD scale into HV, HK, HB value; Convert the value of HRE scale into HV, HK, HB value; Convert the

    value of HRF scale into HV, HB value.
