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-DD-MS，檢測(cè)樣品的蠕變特性。

Checkline RX-DD-MS For the technician that must perform hardness tests on various types of non-metallic materials, we offer the Multi-Scale durometer test kit.

The Multi-Scale base kit consists of a digital display with a type A, D and OO durometer barrel. A complete kit is supplied with a digital display and type A, D, B, C, DO, O, OO, OOO durometer barrels.

Check-Line RX-DD-MS Changing scales is accomplished by unscrewing one barrel and replacing it with another - no supplementary calibration or adjustments are necessary.

A test block, calibrated to the selected scale is also included. The block allows the user to perform quick functional checks on the instrument.

The indicator and barrels are made in the USA, and are calibrated to the ASTM-D2240 standard for durometer hardness testers.
