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-4000硬度計(jì)底座，通過(guò)把手固定硬度計(jì)，砝碼和測(cè)試樣品。

The RX-4000 Digital Durometer is the perfect instrument for use on the production floor or in the lab for measuring the hardness (Durometer) of rubber and plastic parts. It features an over-sized 18mm footer, large LCD display with USB output. Available models include RX-4000-A for Rubber Parts and RX-4000-D for plastic parts.

The Model 4000 Digital Durometer is supplied in a foam-fitted carry case along with an NIST-Traceable Calibration Certificate.
