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。

CHECK-LINE HP Series durometers are designed to measure the hardness or firmness of a wide variety of parts and test samples. This unit is designed in accordance with ASTM and DIN quality standards which specify the bottom contact area (working diameter), sensing pin configuration and internal spring forces. Additionally, the displacement of the sensing pin, relative to the dial indicator, is specified by these standards.

The Checkline HP Series provides an analog dial indicator calibrated for a range of 0-100 Shore units, an optional memory pointer is available to record the highest recorded reading.

All CHECK-LINE Durometers feature a unique spring-operated test pressure shell, which helps assure that similar test pressures are used for each measurement. This system significantly enhances the measurement repeatability, especially between different operators.

Oversized flat bottom surface makes position of working face (area of contact as specified in ASTM/DIN Standards) convenient and consistent which limits variability between operators.
