Its compact design and user-friendly interface make it ideal for marine biologists and aquarium enthusiasts seeking reliable, on-the-go testing to maintain optimal reef health. ## Description HI772 Hanna checker for testing in saltwater applications. The HI772 (Handheld Colorimeter) 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. Review: Must have - Effective, accurate and high quality.
