Abstract

PURPOSE: To enable to cope with various hardness measurements with one set of hardness meter, by providing the pressure unit selection set through simple selection of reference weight.
CONSTITUTION: The reference weight coil springs 15 to 17 are externally coupled to the pressure unit axis 1, they are supported with the axis 1 via the spring holders 1c, 12 to 14, female screw hole 18 is placed under the support cylinder 3, the three types of operational cylinders 19 different in thickness is made removable, and fitting nuts 4, 4' are made removable under the lower end of the axis 1. Thus, the operation cylinder 19 of desired thickness is mounted to the female screw hole 18, and the coil springs 15 to 17 for reference weight are selectively compressed for required number, allowing to easy selection of the reference weight. The fitting nuts 4, 4' are mounted to the axis 1, 1 or 2 pressure unit holder 1a or 6 is fitted to the axis 1 to achieve desired purpose.
