動的硬度計。 a load means; an indenter pressed against the surface of the test object by the load means; a displacement detection means for detecting the amount of displacement of the indenter; and a displacement detection means for outputting a load signal to the load means and inputting from the displacement detection means. In an indentation depth type dynamic hardness tester, the indentation depth type dynamic hardness tester is provided with a control means for storing and calculating signals, and a recording means for recording a load-indentation characteristic curve based on the load and displacement signals output from the control means. The stored displacement signal from the displacement detection means when the indenter contacts the surface of the test object and the displacement signal from the displacement detection means after the indenter starts to be pressed are input, and a displacement signal proportional to the difference between the two signals is generated. An indentation depth type dynamic hardness meter characterized by being provided with a differential amplifier for outputting to a recording means.
