MICRO HARDNESS TESTERS
Built in dial-a-weight system easily changes from load to load.
CM Series Micro Hardness Testers
As a variety of new materials are being introduced to the market, the need for Vickers and Knoop micro hardness testing has greatly increased. CM Series Micro Hardness Testers utilize advanced technology for incredibly accurate test results. And for optimum flexibility, combine the CM Tester with our available ARS Software, for a complete automated testing system.
Special Features
- Built in dial-a-weight system easily changes from load to load.
- Advanced microcomputer with LCD touch panel display (CM-802/CM-802AT)
