Wide Range ClO₂ Test Strips

Wide Range Chlorine Dioxide Test Strips (0–500 ppm) Our Wide Range Chlorine Dioxide Test Strips offer fast and accurate measurement of chlorine dioxide concentrations from 0 to 500 ppm. Designed for use in food processing, industrial sanitation, and water treatment, these strips use a redox indicator and buffer system to deliver reliable colorimetric results Key Features: Broad-Range Detection: Measures chlorine dioxide concentrations from 0 to 500 ppm with a visible green color change Quick Results: Color develops rapidly based on ClO₂ concentration — ideal for on-site testing No Reagents Needed: Simple, portable design for immediate field or facility use Versatile: Effective in food processing plants, cooling towers, agriculture, and other high-dosing environments Performance Notes: The reaction of chlorine dioxide with the redox indicator yields a green color proportional to the amount of chlorine dioxide present. Chlorine*, Bromine, iodine, permanganate, and monopersulfate will deliver a positive interference with these test strips. Hydrogen peroxide, even at 3%, does not interfere. No significant interference is noted when testing with 5 ppm iron, copper or manganese, 20 ppm quat, 40 ppm polyquat, chelant to remove 5 ppm metals, 1 ppm copper algaecide, at pH 6-8.4, at temperatures 15C-40C, nor with 100 ppm cyanuric acid.*No inhibitor is included for this formula so chlorine (free or combined) at any level will likely interfere.
