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 RX-1600-A120专为冰鞋行业而设计，测量滑板轮的硬度。

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.
