溝用硬さ測定装置。 A guide tube is installed almost vertically in contact with the surface to be measured of the specimen whose hardness is to be measured, and a ball indenter is guided through the guide tube and is movable and comes into contact with the surface to be measured. The hammer is equipped with a hammer having a measuring part made of a magnetic material, and the hammer is injected and collided with the surface to be measured by a constant pressing force of an injection compression spring, and the bounce state is electrically measured to determine the hardness. A hardness measuring device for measuring hardness includes a replenishing guide tube fixed to a guide tube via a joint and inserted into a groove forming a surface to be measured, and a replenishing guide tube fixed to a hammer and guided through the replenishing guide tube. A hardness measuring device for a groove, characterized in that it is equipped with a replenishing rod having a ball indenter at its tip.
