The digital display surface Rockwell hardness tester is a high-tech product with high precision and stable performance. The interface is menu-based and the operation is simple, intuitive and convenient. The measuring device is controlled by a grating displacement sensor and ARM32 chip. It is a mechanical and electrical integration hardness testing instrument. Suitable for measuring various metal materials of surface hardened steel, copper, aluminum alloy sheet, strip steel, cemented carbide steel, galvanized, chromium, tinned, material surface heat treatment and chemical surface treatment
Integrally cast body:
The body part of the product is formed at one time by the casting process, and after a long time aging treatment. Compared with the puzzle process, long-term use of deformation is extremely small, and can effectively adapt to various harsh environments.
Control System:
The motor is used to control the loading, loading and unloading of the test force, eliminating the manual operation errors of the manual Rockwell hardness tester; the LCD screen display interface can be used to display and set the current test scale, test force, test indenter, and load holding time , Hardness conversion type, etc.
