The peroxide test strip detects residual peroxides, for example, in drinking water, pools, and hot tubs where hydrogen peroxide is used as a disinfectant. Recommended peroxide levels vary, therefore the test strip can be used to test the concentrations users prefer.
Extra high level peroxide strips are used to test concentration levels of peroxide solutions used in cases where strong disinfection is needed. This test strip is designed to work with solutions prepared from concentrated hydrogen peroxide only. It should not be used to test solutions made using “accelerated” hydrogen peroxide products.
