The Hanna Total Chlorine Checker® bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits have limited accuracy and resolution since they rely on the human eye to discern differences in colour. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Hanna Total Chlorine Checker® uses a fixed wavelength LED and silicon photodetector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.
The HI711-25 are the replacement reagents for the HI711 Total Chlorine Checker®HC. These high-quality reagents are manufactured in Hanna Instruments state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.
