Hanna Instruments HI711 Total Chlorine Checker® HC

The Hanna Total Chlorine Checker® serves as a transitional tool between inexpensive chemical test kits and sophisticated equipment. Chemical test kits rely on the human eye to distinguish changes in hue, which limits their accuracy and resolution.

To precisely determine ion concentration, professional instrumentation combines a light source, such as an LED or tungsten lamp, with a filter and a light sensing detector. Professional instrumentation might cost hundreds of dollars but provides superior resolution and precision.

The Hanna Total Chlorine Checker® offers the precision of specialized equipment at the cost-effective pricing of a chemical test kit by utilizing a fixed wavelength LED and silicon photo detector.
