[0001] The utility model belongs to the technical field of hardness measuring instruments, in particular to a comprehensive hardness measuring instrument for building inspection. Background Art

[0002] After the processing of building materials is completed, they need to be tested for hardness using a hardness measuring instrument. When testing the hardness, a hardness testing head is used to squeeze the building materials to be tested, and then the hardness of the building materials to be tested is calculated based on the indentation depth.
