Digital Micro Vickers Hardness Tester

Digital Micro Vickers Hardness Tester

DMV01 Digital Micro Vickers Hardness Tester adopts large LCD screen to display and menu type structure to choice hardness scales HV or HK, exchange hardness values among scales, store testing results and data procession automatically, as well as output by printer. By means of interface of RS-232, the instrument can be linked with computer.

Usage Range:
Heat treated layer, carbonized layer, hardened hard layers, superficial coating, steels, non-ferrous metal, micro and thin shaped components.
