Hanna Alkalinity Colorimeter Checker

The Hanna Alkalinity Colorimeter Checker was born at the crossroads of old-school liquid test kits and advanced, modern technologies. The unique, handheld device is simple to use and provides extremely accurate, reliable readings of carbonate hardness (dKH) in saltwater and marine aquariums. The process is fast and provides more accurate readings than that of simple chemical test kits...which can be the difference between a successful aquarium and disaster. Unlike other measurement devices, this one is focused on a specific parameter to provide unmatched control and absolute certainty.
