The body of the 7MHVS-5A Touchscreen Vickers Hardness Tester is formed through a single casting process and undergoes prolonged aging treatment. Compared to spliced panel construction, this design minimizes long-term deformation and effectively adapts to various harsh environments. It is suitable for hardness testing of ferrous and non-ferrous metals, IC thin sheets, surface coatings, laminated metals, glass, ceramics, agate, gemstones, thin plastics, as well as the depth and gradient of carburized and quenched layers. It is particularly well-suited for precision Vickers measurements of parallel planes, micro-components, and ultra-thin parts.
