Product information "HI772 Checker HC ® - MARINE Alkalinity (dKH)"

The HI772 Checker®HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure alkalinity in degrees of calcium hardness, commonly abbreviated as dKH. Critical to marine environments, alkalinity not only provides the carbonate ion required for calcium carbonate skeletal regeneration of coral reefs, but it also acts as a pH buffer against large changes in acidity.
