Get accurate results for your saltwater aquarium with this simple handheld colorimeter.
The Hanna 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. The Hanna handheld colorimeter eliminates the hassle of matching to a color chart by providing a direct saltwater alkalinity result in dKH units.
- Portable and fits right in your pocket.
- Simple, one-button operation makes getting your alkalinity results easy.
- Improve your testing routine and upgrade from your standard test kit
