硬度計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、維氏硬度計、顯微硬度計、布氏硬度計、邵氏硬度計、巴氏硬度計、里氏硬度計、韋氏硬度計、肖氏硬度計、布洛維硬度。根據(jù)使用方式:便攜式硬度計、臺式硬度計。

Introduced in 1965, the Model 1700 was designed to enable the user to observe and measure the "creep" present in a specimen. Creep refers to the tendency of the durometer indentor to continue to penetrate a specimen over time, giving lower durometer readings. For example, if the durometer is held against a specimen in full contact and with constant pressure, the durometer reading will decrease over a period of seconds after the initial reading is taken. So, in a specimen with creep, the initial reading may be 35.0 durometer points, while the reading after three seconds may be 33.5 durometer points. The Model 1700 features a max- hand and an active hand so that creep may be observed. The max hand holds the maximum reading while the active hand can be observed creeping down the scale. The 1700 is equipped with a max-hand reset button on the top left of the gauge.
