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-1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。

The Check-Line OS-1 Operating Stａnd is the ideal tool for repetitive or lab-type testing for users who must test either very large specimens, or test in a number of different durometer scales. The OS-1 Operating Stand, used in conjunction with adurometer eliminates the operator error sometimes associated with shop floor durometer testing. The stａnd features a floating pin and includes the proper load weights required for testing in durometer scales (A, B, C, D, DO, E, O, OO, and OOO), as noted in ASTM D2240. The OS-1 includes (2) weights - the thin weight is used for the Type A, B, O (approx 1kg), the thin and thick weights are used together for Type D, C, DO (approx 5kg), and if you remove both weights you can do Types OO and OOO.

The OS-1 can accommodate specimens varying in size from a 1/4: to 10 inches thick. (custom stands for testing larger specimens available) Checkline OS-1
