Electric surface Rockwell hardness tester(HRM-45DT)
The electric surface Rockwell hardness tester adopts an automatic loading and unloading test force mechanism, and the test force conversion is obtained by the rotation of the variable load hand wheel;The operation is simple and rapid, and there is no artificial operation error except for the dial to zero, which has high sensitivity and stability;Suitable for workshops and laboratories. It has been widely used in all walks of life.
Main features and features:
1. The hardness value is directly read through the dial pointer, the pointer is sensitive, and the measured result is higher than the national standard;
2. The shell is formed by a special sand-casting process. The structure is stable and not deformed, and it can work under harsh environment. The car paint has high grade and strong scratch resistance. It is still bright and new for many years.
3, test force: application, load, unloading automatically completed;
4. We have the ability to develop and design, manufacture and process our own machines. Our machines provide replacement and maintenance upgrade services for life.
Main use and scope of application:
1. Hardened steel, quenched and tempered steel, annealed steel, bearing steel, strip steel, hardened steel sheet, hard alloy, etc.
