Introduction
HRS-150 Digital Rockwell Hardness Tester is a high-tech product with high precision and stable performance. The interface is menu-based, and the operation is simple, intuitive and convenient. It is widely used to measure the Rockwell hardness of ferrous metals, non-ferrous metals, non-metallic materials, quenched and tempered and other heat-treated materials. Such as cemented carbide, carburized steel, hardened steel, surface hardened steel, hard cast steel, aluminum alloy, copper alloy, malleable casting, mild steel, quenched and tempered steel, annealed steel, bearings and other materials.
Integral casting body:
The fuselage part of the product is formed at one time by the casting process and has undergone a long-term aging treatment. Compared with the paneling process, the long-term use deformation is extremely small, and it can effectively adapt to various harsh environments.
Control System:
Intelligent digital Rockwell hardness tester, in addition to load selection, realizes automation;
The automatic loading, holding and unloading of the test force is controlled by the motor, which eliminates the manual operation error of the manual Rockwell hardness tester;
The LCD display interface is used to display and set the current test scale, test force, test indenter, dwell time, hardness conversion value type, etc.;
