Used for rapid detection and quantification of hydrogen peroxide residues in water, food processing equipment, and pharmaceutical systems. Ideal for monitoring sanitization processes where peroxide is used as a disinfectant. Commonly applied in breweries, dairies, and clean-in-place (CIP) systems to ensure complete rinsing and prevent product contamination. Test helps maintain safety and compliance by verifying peroxide levels are within acceptable limits before production resumes. Suitable for field and lab use due to simple colorimetric readout.
