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-2000，测量塑料，泡沫和橡胶硬度。

The RX-2000 durometer is the latest innovation for the testing of specimens with creep. The RX-2000 has a second needle which holds the highest measurement. This helps the operator observe the creep characteristics of a specimen. To reset the peak indicator the user simply rotates the reset knob on the front of the gauge to clear the previous reading. The simplicity of the reset mechanism ensures a lifetime of use, and makes the RX-2000 the most affordable durometer for testing specimens with creep.

RX-2000是一款创新的硬度计，通过蠕变测样品。RX-2000有第二根针，保持的测量值，这样操作者可以观察样品的蠕变特性。重置峰值指示，用户只需要简单地旋转面板前的重置按钮，清除之前的读数。复位机制很简单，使得RX-2000非常。
