Free Chlorine Checker HC
Simple, accurate and cost effective way to measure free chlorine.
Free Chlorine Checker HC - HN/000701
The Free Chlorine Checker bridges the gap between simple chemical test kits and professional instrumentation.
Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in color.
Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine absorbance and ion concentration.
Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars.
The 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.
