Scratch Hardness Tester Motorized is a unique test instrument to determine the resistance to scratch under a specified load. Tests are conducted either on a go/no go basic by testing at a single specified load on the diamond stylus tip or by increasing loads to determine the minimum load at which the coating is Penetrated. PRESTO Scratch Hardness Tester is designed as per standard ISO 1518-1
