Platinum-Cobalt/Hazen/APHA Color Scale, Lovibond® - 0-70mg Pt/l - 433280

The Lovibond® AF328 is a special kit for visual color grading of Platinum-Cobalt/Hazen/APHA Color over the range 0 – 70mg Pt/l. It is typically used for light yellow liquids such as water, oils and chemicals. The color is determined by visually matching a column of sample in a Nessler cylinder with precalibrated colored glass standards, which are stable-colored and not affected by UV light or extreme environmental conditions. Because the sample colors are relatively unsaturated, the kit employs a long path length Nessleriser comparator to give greater measurement sensitivity and accuracy. Includes: Nessleriser 2250 with Daylight 2000 Lighting Unit and Nessler cylinders, Pt-Co/Hazen discs CAA & CAB, and stand for using Nessleriser with natural lighting.
