Alkalinity DKH Colorimeter HI772 Hanna Checker - Marine Water

The Hanna Alkalinity Checker is a simple tool that helps you easily check the alkalinity levels in your aquarium, displaying the results in dKH. It features a large LCD screen for clear readings and a straightforward three-step process: just zero the instrument with your water sample, add the reagent, and read the results. This device is designed for easy maintenance and consistent performance, making it a great choice for beginners and experts alike.

Easier to Use and More Accurate than Chemical Test Kits

Chemical and titration test kits have limited accuracy and very hard to repeat that usually will rely on the human eye and lighting to determine the reading. Hanna's HI772 Alkalinity Checker is much more reliable with their single light source with a fixed wavelength that will give the electronic checker the ability to make repeatable measurements time after time. Similar measurement devices are used by labs and large-scale testing facilities for their dependable and precise measurements.
