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 OS-2硬度计底座，和不同刻度的硬度计配套使用，减少人为操作失误，提高测量精度，是工厂现场和实验室的不二之选。

ELECTROMATIC Equip't introduces the Checkline OS-2 compact operating stand for durometers in the A, B, E and O scales. The stand, used in conjunction with our Durometers, eliminates operator error sometimes associated with shop floor durometer testing. The stand features a load weight for the proper testing pressure as noted in ASTM D2240, and a quick-lock column for easy adjustment. It can be used with either the provided specimen holder or the optional O.R.F.-1 O-Ring Fixturing Set (sold separately).

The Check-Line OS-2H features an a dampener that lowers the durometer at the same rate for each test, resulting in superior repeatability for all durometer tests
