Macro Vickers hardness tester BHV series

micro Vickersbenchtopfor plates

Product Overview
The BHV-5/10/30/50TPTA Vickers hardness tester is designed for precise micro- and macro-Vickers testing of metallic and certain non-metallic materials. It supports measurement on tiny parts, thin sheets, metal foils, wires, thin hardened layers and electroplated coatings, and can evaluate internal hardness of induction-hardened or carburized layers by following microstructural features. The instrument integrates optical, mechanical and electronic systems, with high-reliability components, touchscreen operation and repeatable measurement procedures.
