The use of a Chlorine Dioxide Test Strip can provide fast and reliable monitoring of chlorine dioxide levels, including residuals. The Low Level Chlorine Dioxide Test Strips detect levels from 0-10ppm in increments of 0, 0.25, 0.5, 1, 3, 5, and 10 ppm. Chlorine dioxide has a higher oxidation capacity than chlorine or ozone, which means lower concentrations of chlorine dioxide can be used to achieve effective disinfection. It can also be used when large amounts of organic matter are present.

-Dip test strip into test solution and slowly wave back and forth for 5 seconds. -Wait 15 seconds and then compare the test pad with color scale. *Note: Solutions with a concentration greater than 20 ppm will show as a mottled brown color on test pad.
