    HBRV(D)-187.5D1

    Electric Brinell, Rockwell and Vickers Three Way Hardness Tester

    HMRV(D)-45D1

    Electric Surface Rockwell & Vickers Hardness Tester

     Main Features

    • It has three hardness test methods of Brinell, Rockwell, and Vickers.
    • Direct reading of dial hardness value.
    • Automatic loading and unloading- keeping-unloading, simple operation, no artificial operation error.
    • Stable performance, simple operation and convenient use.
    • Optimized design of a mechanical structure, low electrical power consumption, linear small circular arc appearance.
    • Strong structure, good rigidity, accuracy, reliability and durability, and high-test efficiency.

    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.
