About KHZKHC 2-9 Scratch Tester Hardness

Product specifications: - Different levels of hardness represent differences in the firmness of the internal molecular structure of the object. - When an object with a strong molecular structure touches an object with a weak molecular structure, the latter's molecular structure will break, causing so-called scratches. - When measuring the Mohs hardness of industrial floors, we mark the Mohs hardness pen on the industrial floor that has been completed. The marking hardness tests are conducted in order from low to high. - Generally speaking, after each test, you should observe whether there are scratches on the ground. If there are no scratches on the ground, the actual hardness of the ground is greater than the hardness of the Mohs hardness pen.
