一般描述
(free chlorine, total chlorine, ａnd pH) Method: colorimetric with color-matching vessel 0.1 - 0.3 - 0.6 - 1.0 - 1.5 mg/l Cl? pH: 6.8 - 7.1 - 7.4 - 7.6 - 7.8 MQuant®
Chlorine containing disinfectants are most widely used. They are applied particularly to disinfect drinking water ａnd swimming pool water. This MQuant® Chlorine ａnd pH test (formally MColortest®) measures chlorine ａnd pH ａnd evaluates the color reactions based on the transmitted light method. So even turbid ａnd colored water samples can be analyzed without further preparation. The color matching vessel is made of very durable, lightfast plastic, thus suitable for industrial areas ａnd wet environments.
Using the refill packs 1.11143 ａnd 1.11157, the original test kit can be used for a very long time, making it a particularly economical ａnd ecological system.

Method
In weakly acidic solution free chlorine reacts with diethyl-p-phenylenediamine (DPD) to form a red-violet dye. Combined chlorine reacts only after the addition of iodide ions. This permits free chlorine to be distinguished from combined chlorine.
The pH determination takes place by means of chlorine-resistant phenol red indicator solution, which changes color from yellow to red-violet in the pH range of 6.5 8.2.

This test is not suited for seawater.
Water in public ａnd private swimming pools must be disinfecting to kill bacteria ａnd viruses. Chlorine-containing preparations or even chlorine gas itself are usually used for this purpose. To check the content of chlorine ａnd the pH value is essential.
