HARDNESS TESTER AND HARDNESS TEST PROCEDURE

摘要

A hardness tester includes a measuring device (CPU) that measures a value for a material property of a sample in conjunction with the formation of an impression, a sensing device (CPU) that acquires measurement data that matches the value for the material property of the sample that is generated by the measuring device and a determining device (CPU) that accumulates a predetermined value for the material property based on the measurement data acquired by the detection device and determines a timing for exchanging the indenter based on the cumulative value for the material property.
