General description

Method: colorimetric, DPD, with color card and comparator block with long test tubes 0.020 - 0.050 - 0.075 - 0.10 - 0.15 - 0.20 - 0.30 - 0.40 - 0.55 mg/l ClO₂ MColortest^®

Chlorine dioxide is used for water disinfection and as a bleaching agent in industrial processes. The MQuant^® Chlorine Dioxide test (formally MColortest^®) can be used for the determination of chlorine dioxide for example in swimming pool water, drinking water and wastewater. Method In weakly acidic solution chlorine dioxide reacts with dipropyl-p-phenylenediamine (DPD) to form a red-violet dye. The chlorine dioxide concentration is measured semiquantitatively by visual comparison of the color of the measurement solution with the color fields of a color card.The unique brilliance of the print and their fine color graduation allow precise analyses, even at the lower end of the concentration range. Due to the long test tubes a sensitive measurement range can be covered. Using the refill pack 1.18757 containing all the reagents, the original test kit can be used for a very long time, making it a particularly economical and ecological system.This test can be used for •Drinking water•Disinfectant solutions•Boiler and boiler feed water, cooling waterThis test is not suited for seawater.
