The Lovibond® AF328 is a special kit for visual colour grading of Platinum-Cobalt/Hazen/APHA Colour over the range 0 - 70 mg Pt/l.
It is typically used for light yellow liquids such as water, oils and chemicals. The colour is determined by visually matching a column of sample in a Nessler cylinder with precalibrated coloured glass standards, which are stablecoloured and not affected by UV light or extreme environmental conditions.
Because the sample colours are relatively unsaturated, the kit employs a long path length Nessleriser comparator to give greater measurement sensitivity and accuracy.
Applications: Chemicals, Edible Oils & Fats, Petroleum Oils & Waxes, Water & Waste Waters
