详细信息
该仪器具有多种试验力和多种压头,用于测定金属材料或试件的布氏、洛氏、维氏硬度。适用于黑色金属(钢材、铸铁件、软钢、淬火钢等)和有色金属(铝合金、铜合金等)的硬度测定,并可测定硬质合金、滲碳层和化学处理层的硬度。                   
    HBRV(D)-187.5A1型布洛维硬度计采用了旋转式试验力变换机构和光学测量系统,在机体上装有 显微镜测量装置。使用方便,变荷可靠,示值稳定,广泛适用于工厂车间、试验室、大专院校和科研机构。      
    The instrument has a variety of tests and a variety of indenter for the determination of metal materials or samples of Brinell, Rockwell, Vickers hardness. Apply to black metal (steel, cast iron, mild steel, hardened steel, etc.) and non-ferrous metals (aluminum, copper alloys, etc.) the determination of hardness and determination of hard alloy, chemical processing and Carburizationlevel hardness.
    HBRVD-187.5A1 Brinell Rockwell &Vickers Hardness Tester using rotary power conversion and   optical measuring system in the body microscope equipped with measuring devices. Easy to use, reliable and the load changed, showing the value of stability, applicable to the wide range of factory workshops, laboratories , Tertiary institutions and research institutes.
