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.

The practical visual color comparator test that makes measuring free and total chlorine, as well as pH of water samples easy and user-friendly. 

 The pocket-sized test uses long-lasting and cost-efficient reagents, making it the perfect solution for remote locations. 

 Simple, safe and independent!
