Abstract: A hardness tester includes an indenter, an arm and a driver which loads a test force onto the indenter and press the indenter against a sample, a spring displacement amount sensor detecting a value for the test force loaded onto the indenter, and a controller. In a state where a predetermined test force (total test force) is loaded onto the indenter by the driver, when the value of the test force detected by the spring displacement amount sensor exceeds a predefined allowable margin relative to the predetermined test force, the controller executes predetermined processes, including an interrupt process interrupting the test currently being executed and a notification process notifying a user that the value of the test force exceeded the allowable margin during execution of the test.

Abstract: Provided is a hardness tester and method including an indentation former creating an indentation in a sample surface with an indenter; a first area calculator calculating an area of the indentation during application of pressure, the indentation being formed in the sample surface while the indenter is pressed against the sample; an image capture controller controlling a CCD camera to obtain image data of the sample surface; a second area calculator calculating the area of the indentation remaining in the sample surface based on the obtained image data; an elasticity index calculator calculating an elasticity index of the sample based on the area of the indentation during application of pressure and the area of the indentation calculated by the second area calculator; and a hardness value calculator calculating a hardness value of the sample based on the indentation remaining in the sample surface.
