Electric Rockwell Hardness Tester(HR-150DT)
The electric 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 handwheel;The operation is simple and rapid, except for the dial to zero, there is no man-made operation error, and it 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 can be read directly through the dial pointer, the pointer responds sensitively, and the measured result is higher than the national standard;
2.The shell is made of one-time molding and casting by a special sand-finding process, the structure is stable and does not deform, and can work in a relatively harsh environment; the car paint has high grades, strong scratch resistance, and it is still bright as new after years of use;
3.Test force: applying, holding and unloading are automatically completed;
4.We have the ability to develop, design, produce and process by ourselves, and provide parts replacement and maintenance upgrade services for our machines 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.;
