1. Purpose
The electric Rockwell hardness tester adopts Automatic loading and unloading test force mechanism, the test force transformation is obtained by the rotation of the variable load handwheel; the operation is simple and fast, except for the dial to zero, there is no artificial operation error, and it has high sensitivity and stability;< span style=”font-family: arial, helvetica, sans-serif; text-indent: 42px;”>for workshops and laboratories. It has been widely used in all walks of life. Hardened steel, quenched and tempered steel, annealed steel, bearing steel, strip steel, hardened sheet steel, cemented carbide, etc.;
Second, features
1. The hardness value can be read directly through the dial pointer, the pointer is responsive, and the measured result is higher than the national standard;
2. The shell is cast by a special sand casting process, the structure is stable and non-deformed, and it can be used in relatively Working in harsh environments; high-grade car paint, strong scratch resistance, and still bright as new after many years of use ;
3. Test force: application, maintenance and unloading are completed automatically;
4. We have the ability to develop and design, produce and process by ourselves, and our machines provide parts replacement and maintenance upgrades for lifeService.
