摘要： A hardness tester includes a correlation memory storing correlation data which associates hardness of a standard reference sample based on dimensions of an indentation formed by pressing an indenter into a surface of the standard reference sample, and hardness of the standard reference sample based on test force and depression amount during formation of the indentation in the standard reference sample. A CPU measures the test force and depression amount during formation of the indentation in a measured sample; calculates an estimated value of the hardness of the measured sample based on the measured test force and depression amount; and calculates the hardness of the measured sample based on the calculated estimated value and the correlation data.

摘要： A hardness tester forms an indentation on a surface of a sample by loading a predetermined test force with an indenter and measures a hardness of the sample using the indentation. The hardness tester includes a light source emitting light on the surface of the sample and forming an illumination pattern having a spot; and a controller forming the indentation by bringing the indenter into contact with the sample in a state where a perpendicular line of a vertex of the indenter overlaps a test point when the position of the spot of the illumination pattern formed by the light source on the surface of the sample is used as the test point.

摘要： The hardness tester includes a plurality of weights; a transmission mechanism transmitting to an indenter a force of gravity acting on the weights; and a test force switching mechanism switching between magnitudes of a test force. The weights include hollow portions running through the weights in a vertical direction; and accommodation portions formed so as to be capable of accommodating the weight directly below. Outside tapered portions are provided to an exterior surface of the weights and inside tapered portions are provided to an interior surface of the accommodation portions. The transmission mechanism includes a shaft member and a weight engagement portion capable of being accommodated by the bottom-most accommodation portion to engage a weight. The weight engagement portion includes a tapered portion engaging the weight to regulate horizontal-direction displacement. A predetermined gap is reserved between the hollow portions and the shaft member.
