The Hanna Marine checkers are the ultimate when it comes between chemical reaction test kits and professional instruments using colorimeter. Chemical test kits have limited accuracy and resolution since they rely upon the human eye to tell differences in color and when it changes. Hanna testing instruments incorporate a led light source with a filter and a light sensing detector to precisely determine the test results. Professional hanna instruments offer greater resolution and accuracy. These checkers use a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrument test kits at the affordable price of a chemical test kit.
