Low Range Test Strips Descriptions: 

The low range series test strips for measuring chlorine dioxide incorporates the following: a redox indicator, buffer, and chlorine inhibitor. These test strips are formulated to test chlorine dioxide via colorimetric analysis in the range of 0-10 ppm.



The reaction of chlorine dioxide with the redox indicator yields a pink color proportional to the amount of chlorine dioxide present. These strips inhibit 1.5 ppm chlorine or greater. Bromine, iodine, and permanganate will deliver a positive interference. Free chlorine above 2 ppm will also deliver a positive interference. High levels of chloramine and monochloramine will slowly interfere with the accuracy of chlorine dioxide measurement. Hydrogen peroxide, even at 3%, does not interfere. Chlorite does not yield a positive interference (up to 750 ppm) nor does it consume or interfere with the chlorine inhibitor. No other 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. 100 ppm cyanuric acid may affect the accuracy of the test strip, causing low colorimetric readings.
