Rockwell Hardness Tester – Digital


Application Standards

ASTM E18, EN ISO6508, GB/T230.2, JJS Z2245


Digital Rockwell hardness testers are advanced instruments used to measure the hardness of materials with precision and efficiency. Unlike traditional analog models, these testers feature digital displays and controls, enhancing accuracy and ease of use. They utilize a controlled force to indent the surface of a material and measure its resistance to penetration, providing a numerical hardness value. Digital Rockwell testers offer various scales to accommodate different materials and testing requirements, such as regular and superficial Rockwell scales. Additionally, they often incorporate automated features like automatic loading of test forces and data recording, streamlining the testing process and reducing human error. With their versatility, reliability, and digital capabilities, these testers are essential tools in industries such as manufacturing, metallurgy, quality control, and research, enabling precise assessment of material hardness for diverse applications.


Digital Rockwell hardness testers are indispensable in various industries for assessing the hardness of diverse materials. They ensure optimal hardness levels for hard alloys and surface-hardened steel, crucial for durability. In copper alloys, they verify hardness variations essential for machining precision. For carburized steel, they gauge surface hardness, enhancing wear resistance. Similarly, they evaluate the hardness of hard cast steel and malleable castings, aiding in process optimization. When assessing annealed steel, they confirm proper softness for machining. Conversely, for hardened steel, they verify desired hardness post-heat treatment. In aluminum alloys, they determine hardness for structural applications. Furthermore, they assist in material selection for specific applications in soft steel and ensure appropriate hardness for load-bearing capabilities in bearing steel.
