"Aolongxin" fully automatic convex nose surface Rockwell Hardness Tester is a large platform Rockwell Hardness Tester, which adopts Rockwell (ROCKWELL) measurement principle and is used for hardness testing of carbon steel, alloy steel, cast iron, non-ferrous metals, engineering plastics and other materials. The "Aolongxin" platform lifting and convex nose Rockwell Hardness Tester adopts the world's most professional closed-loop sensor control technology to achieve fully automatic control and hardness testing process. The "Aolongxin" loading system uses a high-precision force sensor and a central controller to form a closed loop to achieve microsecond-level tracking and control of the entire force-adding process. It is widely used in testing, scientific research and production in metrology, machinery manufacturing, metallurgy, chemical industry, building materials and other industries.

·High-precision loading system effectively avoids force measurement overload and greatly improves the loading speed;
·High testing accuracy and wide measurement range;
·Upper and lower limit settings, out-of-tolerance alarm;
·Surface correction, automatic correction of cylindrical and spherical surface measurement results;
·The specially designed indenter extends in the horizontal direction and can measure parts such as rings and tubes that cannot be measured by ordinary Hardness Testers. The minimum test inner diameter is 40mm;
·Displacement sensor resolution 0.1HR;
·Hardness repeatability accuracy 0.5HR;
·High-speed step control, extremely fast test speed (1.75s);
·Easy to operate, Chinese and English interfaces can be switched (other language versions can be customized)
· Ready to use after power-on, no need to install weights, easy to install and debug;
·Electric loading, closed-loop control;
·The test force is automatically corrected, and the force value accuracy is improved by one order of magnitude.
·Automatic lifting platform and automatic load initial test force can ensure stable generation of force measurement;
·Testing process curve display can visually display material properties and facilitate observation and learning;
·All Rockwell scales have three levels of hardness values: high, medium and low, automatically corrected
·Set password to protect setting parameters; keep more sample and test information
·Adopts modular design and is easy to maintain.
