The Total Chlorine Checker® bridges the gap between chemical test kits and professional instrumentation. Simple chemical test kits have limited accuracy and resolution since they rely on the human eye to observe differences in color. Professional instrumentation have an integrated light source such as an LED or tungsten lamp with a filter and a light sensing detector to accurately determine absorbance and ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Hanna Free Chlorine Checker® uses a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.
