High-Range ClO₂ Test Strips (1–2500 ppm) — 50 per bottle — are precision semi-quantitative strips designed to verify chlorine dioxide concentrations in high-demand sanitizing, deodorizing, and remediation applications. These strips rapidly measure ClO₂ levels from low disinfectant ranges up through industrial-strength solutions, allowing cleaning professionals, remediation techs, and safety personnel to confirm proper dosing on-site. Accurate readings help ensure solutions are effective against microbes, compatible with surface disinfection and odor control tasks, and positioned safely within operational protocols. Ideal for surface sanitation, mold and odor remediation, HVAC sanitization, agricultural and disaster response uses, these strips deliver fast, easy “dip-and-read” results to support consistent, safe, and compliant ClO₂ application monitoring.
