を特徴とする硬度測定装置。[Claims for Utility Model Registration] 1. A device body includes at least an indenter slidably supported so as to protrude outward from its pressurizing surface, a spring member that applies a predetermined pressing load to the indenter, and the indenter. In addition to providing a displacement detection means for detecting the displacement caused by pushing the sample into the sample,
calculation means for calculating the hardness of the sample based on the displacement detected by the displacement detection means, a spring constant of the spring member, a constant due to the shape of the indenter, and an amount of protrusion;
A hardness measuring device characterized in that a display means for displaying the calculation result of the calculation means is provided inside the device main body or separately from the device main body. 2. An indenter slidably supported so as to protrude outward from the pressing surface of the main body, a spring member that applies a predetermined pressing load to the indenter, and a displacement detection means that detects the displacement caused by pressing the indenter into the material. A hardness measuring device characterized in that the weight of the device main body is set to be larger than the pressing load set by the spring member.
