Hanna Checker Low Range Phosphate Colorimeter HI713

HI7134 Phosphate Low Range Checker® Handheld Colorimeter (HC) 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 at a specific wavelength and a light-sensing detector to precisely determine absorbance and ion concentration. The Pool Line Low Range Phosphate Checker HC 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.

• Precise measurements with no guessing of color
• Laboratory measurements at a fraction of the cost
• Simple, intuitive operation
