Chlorine dioxide (ClO2) is widely recognized as a highly efficient, broad-spectrum, and A1 level safe disinfectant, widely used in fields such as drinking water disinfection and food safety microbial control. In order to ensure disinfection effectiveness, different industries have certain requirements for the concentration and residual concentration of chlorine dioxide used for disinfection. To eliminate the tedious operation of preparing reagents and testing processes for users, and improve detection efficiency, based on the GB 5750.11-2006 standard, this product has been launchedWater quality chlorine dioxide detection reagent.

Water quality chlorine dioxide detection reagentTesting precautions

1. For more accurate testing, the reagent blank value should be measured every 3 months. The determination of reagent blank is also carried out according to the testing steps, except that the sample is replaced with pure water for testing. Subtract the blank value of the reagent from the final test result;

2. 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;

3. Chlorine dioxide (II) reagent is a white or light gray powder. If the reagent clumps or turns black, please stop using it and contact the production enterprise;

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

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

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

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