HBRVU-187.5型布洛維光學(xué)硬度計(jì)采用了旋轉(zhuǎn)試驗(yàn)力變換機(jī)構(gòu)和光學(xué)測量指示系統(tǒng),在機(jī)體上裝有壓痕測量裝置。本機(jī)具有多種試驗(yàn)力和多種壓頭,用于測定金屬材料或試件的布氏、洛氏、維氏硬度,是一臺(tái)可以用不同試驗(yàn)方法來測量材料硬度的多用硬度計(jì)。
該機(jī)廣泛適用于黑色金屬、有色金屬和硬質(zhì)合金及滲碳層與化學(xué)處理層的硬度測定。被廣泛用于工廠車間、實(shí)驗(yàn)室大專院校和科研機(jī)構(gòu)。
Model HBRVU-187.5 Brinell Rockwell &Vickers Optical Hardness Tester carries a series of rotating testing force and Optical measurement indication system, and owns pressure trace measuring device. It fits different types of testing force and indenter, which are usually used to measure the Brinell Rockwell &Vickers hardness of metal materials or spicemen. In a word, it is a multipurpose durometer which can measure hardness by various of testing means.
This device is widely used in the testing of black metal, non-ferrous metal, carbide alloy, acieration tier and chemical treatment tier, and normally used in factory workshops, labs, universities and colleges, and institution for scientific research.
