HBRVU-187.5型布洛维光学硬度计采用了旋转试验力变换机构和光学测量指示系统,在机体上装有压痕测量装置。本机具有多种试验力和多种压头,用于测定金属材料或试件的布氏、洛氏、维氏硬度,是一台可以用不同试验方法来测量材料硬度的多用硬度计。
该机广泛适用于黑色金属、有色金属和硬质合金及渗碳层与化学处理层的硬度测定。被广泛用于工厂车间、实验室大专院校和科研机构。
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.
