: When a reagent is added to a water sample, it reacts with the available chlorine to form a colored compound.
: Results are obtained by comparing the sample's color to a standardized color chart or by using a photometric device like a colorimeter for higher precision. Key Testing Methods Chlorine Test Kit Colorimetric
The core of colorimetric testing is the relationship between chemical concentration and color intensity. : When a reagent is added to a
Two primary chemical methods dominate the market: DPD and OTO. Chlorine Test Kit Colorimetric
: The intensity of the resulting color is directly proportional to the chlorine concentration.
