Product Features:
- MBRV-187.5Eis a multi-functional universal hardness tester featuring three test methods (Brinell, Rockwell, Vickers) and seven test forces, meeting diverse testing requirements.
- After applying the preliminary test force manually, the loading, dwell and unloadingof the total test force are completed automatically.
- With wide application and easy operation, it is an essential hardness tester for industrial and mining enterprises as well as research institutes.
- Integrated cast iron structure, electric test force application.
- Stable structure and convenient operation.
Product Application:
- Suitable for hardness measurement of quenched, surface-quenched steel, cemented carbide, cast iron, non-ferrous metals, various normalized and annealed steels, hardened thin steel sheets;also suitable for soft metals, surface heat treatment and chemical treatment parts.
