1.Introduction
HRD-45 electric surface Rockwell hardness tester, using motor automatic control test force loading, holding, unloading process, can choose the load holding time, simple and rapid operation, no artificial operation error, with high sensitivity and stability.
The fuselage part of the product is formed by casting process once and has been treated for a long time. Compared with the technology of plate splicing, long-term use of variable shape is very small, and it can effectively adapt to all kinds of harsh environments.
