According to national standardsGB/T 6234.7-2014Test Methods for Organic Chemical Products, Section7Part: Determination of Melting Color.

The chromaticity detection method of this standard is referencedGB/T 3143Color measurement method for liquid chemical products（HazenUnit, platinum cobalt color code); andGB/T 6234.6-2014Test Methods for Organic Chemical Products, Section6Part: Determination of liquid chromaticity.

This standard is applicable for determining the chromaticity of organic chemical products that are solid at room temperature and have no visible turbidity in the molten state.

The Vista spectrophotometer is excellentColor and haze measurement solutions.

According to the international and domestic standards for measuring the color of molten materials, this instrument has been designed and developed with proprietary testing methods, suitable for measuring the color of organic chemical products that are solid at room temperature and have no visible turbidity in the molten state.

Common chemical products include bisphenol A, phthalic anhydride, maleic anhydride, ethylenediamine, TMA trimellitic anhydride, dimethyl terephthalate, maleic anhydride, DOP， Maleic anhydride, phthalic anhydride, phthalic anhydride, etc.

Other features include automatic calibration, anti overflow sample chamber, and small footprint, all aimed at improving accuracy, lifespan, and flexibility. The Vista spectrophotometer is ready to use out of the box - equipped with everything you need.
