All Purpose Disinfectant Test Strip
Chlorine/Peroxide/Bleach. All purpose test strips.
This is the most versatile test strip. The strip is sensitive to varieties of disinfecting agents, such as, chlorine, bromine, peroxide, iodine or ozone. The strip measures total chlorine. It will react to chlorine concentrations from trace to over 1000 ppm. The strip color will turn from light blue to dark blue, to dark brown. It is a residual chlorine and potency test for bleach, both in one strip. Because of its high sensitivity for peroxide, the strip is also commonly used for detection of residual peroxide in rinse water from RO column after disinfected with peracetic acid.
