Visual Color Comparator Test - Chlorine and pH

Simple, Safe and Independent! The Visual Color Comparator Test is an easy to use tool for measuring free/residual chlorine, total chlorine and pH (acidity) of water samples which is very often convincing in practice!

Why measuring chlorine and pH? In many cases testers want to know if a water was disinfected or if the residual chlorine (=free chlorine) level is still sufficient to protect the drinking water from recontamination. The Ideal level of free-residual chlorine is said to be 0,2-0,5 mg/L. Desinfection with chlorine is more effective at a pH value below 7,5.
