Vickers DM 8 / DM 2 

DM 8 / DM 2


Automatic dead weight hardness tester for micro and macro Vickers and Knoop method, single or multiple indentations. DM8 and DM2 are low cost microhardness testers with high accuracy standards. They are equipped with a motorized rotating turret with combined magnification lenses and indenters for reading and indenting. For micro and macro Vickers and case depth test on all metals: Iron, steel, tempered steel, cast iron, brass, aluminum, copper and metal alloys. Heat treatment, hardening, nitriding, cementation and hardfacing. Knoop test on ceramic and glass materials.
