Hanna Instruments - Checker Handheld Colorimeter Seawater Alkalinity (dKH) coral food potassium and trace elements suchThe Hanna Marine Alkalinity (dKH) Checker 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 such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine absorbance and ion concentration. This level of
