硬度計(jì)是測(cè)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(cè)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(tái)式硬度計(jì)。

進(jìn)口硬度計(jì)，美國(guó)Check-Line RX-1600-A120專(zhuān)為冰鞋行業(yè)而設(shè)計(jì)，測(cè)量滑板輪的硬度。

The new Checkline RX-1600-A120 durometer features a scale specifically designed for testing the hardness of skateboard wheels that measures up to 120 on the "A" scale. Normal type A durometers only read to 100 however as wheel manufacturers began to satisfy the demａnd from riders who wanted harder wheels, wheels with hardness ratings over 100 A became available.

Our Check-Line RX-1600-A120 features a dial that reads from 20 to 120 on the "A" scale to allow wheel manufacturers and riders to accurately measure their wheels in the over 100 range.
