Hanna Checker Nitrate LR

The Hanna Marine Low Range Nitrate Checker® bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits have limited accuracy and resolution as they rely on the human eye to discern color differences. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a light detection filter and detector to accurately determine absorbance and ion concentration. Professional instrumentation provides superior resolution and accuracy, but can cost hundreds of dollars. The Hanna Marine Nitrate Checker® uses a fixed wavelength LED and a silicon photodetector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.
