Residual chlorine colorimeter / residual chlorine tester

The residual chlorine colorimeter, also known as a colorimetric box, is an ideal tool for measuring the concentration of residual chlorine in water treatment plants of various sizes—ranging from large municipal facilities to small-scale industrial or mining operations. It is also suitable for monitoring domestic and industrial water sources. This device offers a simple and rapid method of measurement, making it particularly well-suited for field use where electricity may not be available. The instrument operates based on the visual colorimetry principle using o-toluidine reagent. When a water sample is added to the reagent, the solution turns yellow. The intensity of the yellow color corresponds to the level of residual chlorine present. After the reaction, the sample is placed into a colorimetric holder, and the user visually compares the color against a rotating color wheel with standardized shades. This comparison allows for an accurate determination of the residual chlorine concentration. The measuring range of this device typically spans from 0 to 2.5 mg/L, making it suitable for most routine water quality assessments. Its portability, ease of use, and reliability make it a popular choice for on-site testing in both professional and educational settings. Whether used in water treatment facilities, environmental monitoring, or industrial applications, this colorimeter provides a cost-effective and efficient way to ensure water safety.
