Hanna HI772 Marine Alkalinity (dKH) Checker HC
Get accurate results for your saltwater aquarium with our simple handheld colorimeter digital test kit. The HI772 dKH Alkalinity Checker®HC is our most popular selling aquarium product. Our alkalinity colorimeter bridges the gap between alkalinity test kits and advanced instrumentation. Standard test kits have limited accuracy since they rely upon the human eye to match colors. Our handheld colorimeter eliminates the hassle of matching to a color chart by providing a direct saltwater alkalinity result in dKH units.
Remove the human error from your testing
No need to count drop or titrate your sample
Detects color changes your eye cannot
No calibration required
Get east, quick and consistent results
Accurate and affordable
Cost efficient: Once you purchase the Checker, reagents are sold separately saving money long term
DETAILS
The HI772 Checker®HC (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.
