Platinum cobalt color code visual colorimeter

AF325Platinum cobalt visual colorimeter,AF325Platinum cobalt visual colorimeter2000Series visual colorimeter, when measuring, the colorimetric disc is installed in the colorimeter, and the colors of the left and right fields of view are compared for visual colorimetry. Choosing a lighting system can provide constant observation conditions for chromaticity measurement, improving the accuracy of the measurement. The measurement method is to visually compare the color of the sample to match the chromaticity of a color slide on the color chart.

Platinum cobalt color code（Pt-Co/Hazen/APHA）Used for clear, light yellow liquids, this definition originates from the use ofPt-CoDilute solution with a concentration range from0(Light color) to500(Dark color). standard test methodASTMD1209，AOCSTd1b-64，ISO2211，ISO6271，BS5339This color code is widely used for water quality analysis and colorimetric determination of clean oil, chemicals, petrochemical products such as glycerol, plasticizers, solvents, carbon tetrachloride, petroleum alcohols, etc.1892yearHazenThe doctor first discussed it in the American Chemical AbstractsPt-CoStandard color preparation method, thereafterPt-CoThe color code is thereHazenChromaticity standard orHazenCompany; American Public Health Association（APHA）Standard methods for water and wastewaterPart2120The same method was also adopted in China. So when conducting water quality classification,Pt-CoColor codes are generally equivalent toAPHAColor code.AF325Platinum cobalt visual colorimeter,AF325Platinum cobalt visual colorimeter
