Platinum cobalt chromaticity is a parameter that reflects the saturation of a color, expressed as a percentage. 0% represents colorless, and 100% represents the most saturated color.
Saybolt is a quality control and product identification system specifically designed for refined products with an ASTM color of 0.5 or lower in the petrochemical industry. The product range includes undyed motor gasoline, avgas, jet fuel, naphtha, kerosene, white oil and petroleum wax.
Platinum cobalt chromaticity is generally used for measuring the chromaticity of chemicals, petrochemical products, water quality analysis, etc., such as glycerol, solvents, plasticizers, carbon tetrachloride, petroleum alcohols, etc.
Suitable for measuring the color of liquid chemical products that are transparent or slightly close to the reference platinum cobalt color number, the color characteristic of the tested object is usually brownish yellow.
Gardner's colorimetric cobalt chloride solution, ferric chloride solution, and potassium chloroplatinate solution are mixed in different proportions as standard colorimetric solutions,. Suitable for darker yellow or brownish colors than platinum cobalt. That is to say, oils and chemicals that are generally light yellow to red, including lecithin, resins, dry oils, and fatty acids. Comply with the national standard GB/T 22295-2008 transparent liquid color measurement method (Gardner chromaticity).
The index set for a slightly yellow but colorless petroleum clear liquid with a Sabo characteristic degree. Generally applicable to industries such as mineral oil, kerosene, gasoline, naphtha, etc. It can also be used to detect the color of wax samples and adhesives, and to analyze transparent petroleum liquids.
The SH810 fully automatic petroleum product colorimeter is a specialized instrument designed for liquid color measurement with unique microcomputer control technology. It is exquisite, portable, novel, and unique in design, suitable for laboratory and on-site use. Equipped with factory calibration and user defined calibration functions, the sample cell design is unique and easy to measure and maintain. The platinum cobalt colorimeter adopts a D/0 measurement structure and integrates technologies such as full band light source, single grating light path splitting system, ETC real-time calibration, etc., achieving a resolution of 0.0001, a standard deviation of transmittance within 0.08%, and a chromaticity value of: Δ E*ab 0.015。
