The electric digital display Rockwell hardness tester adopts an automatic loading and unloading force mechanism. The force variation is achieved by rotating the load-changing handwheel. It is easy and quick to operate, without the need to zero the dial. The digital display directly shows the result, eliminating human operational errors. It has high sensitivity and stability, and is suitable for workshops and laboratories. It has been widely applied in various industries.
Main functions and features:
1.The hardness value can be directly read from the digital display screen with a resolution of 0.1, and the measured result is higher than the national standard.
2. Direct conversion between HV and HB hardness units is possible.
3. Low power consumption and long usage time. The digital display head is powered by CR2450 batteries.
4. With time display function;
5. It has a data output function and can be connected to a computer or a micro printer in series.
6. The shell is cast in one piece by a special sand-casting process, featuring a stable structure that does not deform and is capable of operating in harsh environments. The automotive paint is of high grade, with strong scratch resistance, remaining as bright as new even after years of use.
7. Test force: Application, holding, and unloading are automatically completed.
8. We have the ability to independently research and develop, design, and produce and process. Our machines are provided with lifetime services for parts replacement, maintenance and upgrade.
Main uses and application scope:
Quenched steel, tempered steel, annealed steel, bearing steel, strip steel, hardened thin steel plate, hard alloy, etc.
