Our Superficial Rockwell Hardness Tester is ideal for inspecting carburized and nitrided layers on automotive components, as well as testing electroplated parts and galvanized sheets. This Superficial Rockwell Hardness Tester reliably measures thin specimens without penetrating through coatings or hardened layers, thanks to a minimum testable thickness of just 0.01mm and a minimum test force of 1kgf. Despite its low-force design, it delivers laboratory-grade precision that fully complies with GB/T 230.1 and ASTM E18 standards for reliable, repeatable results. Additionally, a built-in diamond indenter protection device prevents damage when testing brittle materials, while quick switching across seven Rockwell scales (including HR15N and HR30N) offers maximum application versatility for diverse shop-floor and lab environments.
