The manual Rockwell hardness tester has stable and reliable performance and is a popular type of Rockwell machine.
It adopts mechanical manual testing and no power supply is required.
It has a wide range of applications, is easy to operate, and features good economic efficiency and practicality.
Main functions and features:
1.The hardness value can be directly read from the digital display screen with a resolution of 0.1. 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 a CR2450 battery.
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, with a stable structure that does not deform, allowing it to operate in harsh environments. The automotive paint is of high grade, with strong scratch resistance, and remains as bright as new even after years of use.
7. We have the capability 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.
