    HBMRRV(M)-250JMT     Intelligent Programmed Digital Display Universal Hardness Tester

     

    Main Features

    • It has three hardness test methods of Brinell, Rockwell, and Vickers.
    • Chinese and English menus, large digital LCD screen, rich menu content, and complete functions.
    • Automatic loading and unloading of load, simple operation, a high degree of automation.
    • Hardness automatic display, high accuracy, small indication resolution, no artificial operation error.
    • It can automatically identify the minimum thickness of specimens and has a super-domain warning system.
    • Automatic conversion among various hardness.
    • It has three national intellectual property rights.

    Application Range

    • Rockwell: It is used to measure Rockwell hardness of ferrous, nonferrous metals and nonmetallic materials. It is suitable for measuring Rockwell hardness of heat treatment materials such as quenching and modulation.
    • Vickers: Ceramics, steel, non-ferrous metals, non-metallic materials, carburizing layer, nitriding layer, electroplating layer. It is suitable for measurement of hardened layer and ultra-thin parts.
    • Brinell: It is used to measure Brinell hardness of ferrous metals, nonferrous metals, nonferrous alloys, and powder metallurgy materials. It is widely used in metallurgy, forging, casting, bearing alloys.
