Ozone sterilization spectroscopy, high efficiency, and no secondary pollution are increasingly being used as an alternative method to chlorine disinfection in drinking water treatment. Ozone is highly unstable in water, and too low a concentration makes it difficult to ensure sterilization effectiveness. Too high a concentration can lead to excessive levels of disinfection byproduct bromate. Therefore, rapid on-site detection of ozone concentration is crucial. To eliminate the tedious operation of preparing reagents and testing processes for users, and improve detection efficiency, this product is launched based on the N, N-diethyl-phenylenediamine (DPD) - potassium iodide methodWater quality ozone detection reagent.

Water quality ozone detection reagentBased on N, N-diethyl-phenylenediamine (DPD) - potassium iodide method. Under the catalysis of potassium iodide, ozone reacts with DPD to produce a red color. The color depth is directly proportional to the ozone content in water.

measuring range

matters needing attention

1. If the content is higher than the reagent range, the measured value can only be used to estimate the dilution factor and cannot be used as a test result. After diluting the sample, retest;

2. This reagent is a white or light gray powder. If the reagent clumps or turns black, please stop using it and contact the manufacturer;

3. The pH value of the water sample to be tested is 5.0-8.0;

4. The measurement should be completed within 1 minute after the completion of color development. Prolonged time will result in inaccurate test results;

5. The triangular positioning mark on the colorimetric tube should be aligned with the positioning mark on the instrument during zeroing and reading;

6. Store in a dry, cool place, out of reach of children. Do not store with food, medicine, etc., and do not put into fire.
