Chlorine is the most common water disinfectant and by monitoring chlorine regularly and accurately, serious health and safety risks can be avoided.
The Hanna Free Chlorine Ultra Low Range 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 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 Free Chlorine Ultra Low Range 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.
The contoured style of the HI-762 ultra-low range Free Chlorine Checker is designed to fit in the palm of your hand. The large LCD is easy to read and the auto shut-off feature ensures the battery life will not be drained if you forget to turn it off.
