一般描述
(free ａnd total chlorine) Method: colorimetric, DPD, with color-disk comparator 0.25 - 0.50 - 0.75 - 1 - 2 - 4 - 7 - 10 - 15 mg/l Cl MQuant®
Chlorine containing disinfectants are most widely used. They are applied particularly to disinfect drinking water ａnd swimming pool water. The MQuant® Chlorine test (formally MColortest®) can be used for the determination of free ａnd total chlorine.

This test can be used in
Swimming-pool water
Drinking water
Wastewater
Disinfectant solutions

This test is not suited for seawater.

Method
In weakly acidic solution free chlorine reacts with dipropyl-p-phenylenediamine (DPD) to form a red-violet dye. In the presence of potassium iodide, also combined chlorine is measured in this reaction. The chlorine concentration is measured semiquantitatively by visual comparison of the color of the measurement solution with the color fields of a color disk. The test evaluates the color reaction based on the transmitted light method. So even turbid ａnd colored water samples can be analyzed without further preparation.
The color disk is made of very durable, lightfast plastic, thus suitable for industrial areas ａnd wet environments.
Using the refill pack 1.18326, the original test kit can be used for a very long time, making it a particularly economical ａnd ecological system.
