硬度计是测量物体硬度的仪器，表示材料抵抗硬物体压入其表面的能力。它是金属材料的重要性能指标之一。一般硬度越高，耐磨性越好。根据所测硬度单位：洛氏硬度计、维氏硬度计、显微硬度计、布氏硬度计、邵氏硬度计、巴氏硬度计、里氏硬度计、韦氏硬度计、肖氏硬度计、布洛维硬度。根据使用方式：便携式硬度计、台式硬度计。

进口硬度计，美国Check-Line RX-1000硬度计，测量泡沫，塑料，橡胶的硬度。

The Checkline RX-1000 Mini-Dial Durometer is both compact and easy to use. Its small dial face and included leather clip-on carrying case make it easy for an inspector to carry the gauge- for work around the shop, or out in the field. The Check-Line RX-1000 durometer holds the maximum reading until reset by pressing the button at the top of the gauge. The max-hold feature and small dial size make the RX-1000 a good choice for hard to reach places, or for out of sight testing.
