硬度計(jì)是測(cè)量物體硬度的儀器，表示材料抵抗硬物體壓入其表面的能力。它是金屬材料的重要性能指標(biāo)之一。一般硬度越高，耐磨性越好。根據(jù)所測(cè)硬度單位：洛氏硬度計(jì)、維氏硬度計(jì)、顯微硬度計(jì)、布氏硬度計(jì)、邵氏硬度計(jì)、巴氏硬度計(jì)、里氏硬度計(jì)、韋氏硬度計(jì)、肖氏硬度計(jì)、布洛維硬度。根據(jù)使用方式：便攜式硬度計(jì)、臺(tái)式硬度計(jì)。

進(jìn)口硬度計(jì)美國(guó)Check-Line Asker X型硬度計(jì)專(zhuān)為測(cè)量橡膠，泡沫，海綿，塑料的硬度
