硬度計(jì)是測量物體硬度的儀器，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)、臺式硬度計(jì)。

進(jìn)口硬度計(jì)，美國Check-Line OS-2硬度計(jì)底座，和不同刻度的硬度計(jì)配套使用，減少人為操作失誤，提高測量精度，是工廠現(xiàn)場和實(shí)驗(yàn)室的。

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
