## Indications for use
E-Z Chek@ Residual Chlorine Test Strips (K100-0101B) provide accurate and convenient means of measuring the concentration of free chlorine remaining in water when rinsing out equipment following disinfection. A rapid screening qualitative method will detect levels above 0.5ppm (mg/L) while the 30 second semi-quantitative method allows interpolation of concentration between Oppm and 5ppm. The qualitative method can be used to determine that chlorine has been adequately rinsed from the equipment. The semi-quantitative method may be useful when corrective measures are undertaken on equipment retaining higher levels of chlorine for extended periods and for testing any containers disinfected with free chlorine (bleach).
