Low Range Chlorine Dioxide Test Strips (0–10 ppm)

Our Low Range Chlorine Dioxide Test Strips provide quick and reliable measurement of chlorine dioxide concentrations from 0 to 10 ppm. Designed for precision in sensitive applications, these strips use a built-in redox indicator, buffer system, and chlorine inhibitor to minimize cross-reactivity and ensure accurate colorimetric readings.

Key Features:

Reliable Low-Range Detection: Measures chlorine dioxide concentrations from 0 to 10 ppm with clear, easy-to-read color change

Built-In Interference Control: Chlorine inhibitor neutralizes up to 1.5 ppm chlorine to reduce false positives

Fast Color Development: Reacts with ClO₂ to produce a pink color proportional to concentration

Simple and Portable: No reagents or instruments required — ideal for on-site testing

Performance Notes:

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.
