Curved Surface Hardness Tester

The curved surface hardness tester applies pressure to a curved sample through an indenter and converts the indentation depth or diameter into a hardness value. It is used to measure the hardness of materials on curved surfaces such as cylinders and spheres, commonly employed in the inspection of industrial components like bearings and pipelines.
Selection
When selecting, consider the type and hardness range of the material being tested to match the corresponding scale; choose the appropriate indenter and support fixture based on the curvature radius of the surface; ensure the instrument's measurement range covers the testing needs, and the operating environment meets temperature and humidity requirements; refer to industry standards to verify accuracy.
