The hardness tester products you will find at PCE Instruments (PCE) are used for determining surface hardness. Each hardness tester uses a standard method of measurement. The measuring principles of most hardness tester devices are based on either the penetration of a diamond indentor into the material being tested or a calculation related to the force of the rebound after striking the tested ...
