Marine Alkalinity (dKH) Checker HC – IC-HI772

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.

Features:
– Easier to use and more accurate than chemical test kits- Dedicated to a single parameter- Small size, big convenience- Ideal for: Aquaculture & Aquariums, Water Quality
