The Hanna Marine Alkalinity Colorimeter Checker (dKH HI772) provides a simple, accurate, and cost-effective way to measure alkalinity in degrees of carbonate 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. Designed as a more accurate alternative to chemical test kits, the HI772 provides quick, accurate results in a few easy steps.
Weighing a mere 65 g (2.3 oz.), the Checker HC easily fits into the palm of your hand or pocket. Use for quick and accurate on the spot analysis. Single-button operation: Zero and Measure Operated by a single AAA battery.
