Hanna Instruments HI701 Free Chlorine Checker® HC
Between inexpensive chemical test kits and sophisticated equipment is a gap that is filled by the Hanna Free Chlorine Checker®. Chemical test kits rely on the human eye to distinguish changes in hue, which limits their accuracy and resolution.
To precisely determine absorbance and 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 Free 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.
