Alkalinity DKH Colorimeter HI772 Hanna Checker - Marine Water
Why does BRS recommend this?
The Hanna Alkalinity checker is an awesome little tool that now will give results in DKH values that are much more common in the aquarium hobby. It will also give you accurate easy to read results with the large LCD display. We like the repeatable results and ability to purchase replacement reagents when needed. The biggest key with Hanna checkers is keeping the vials nice and clean for consistent results.
Uses Hanna HI772-26 liquid reagents
Three simple steps to results. The Hanna Alkalinity Checker bridges the gap between simple chemical test kits and professional instrumentation. Accurate, affordable and easy to use. First, zero the instrument with your water sample. Next, add the reagent. Last, place the vial into the Hanna Alkalinity Checker, press the button and read the results. Done.
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.
Dedicated to a single parameter
Instead of a single unit doing everything, each Hanna Checker is designed to perform a test for a single parameter. This allows the test to have greater precision while also making it easier to use overall.

The tip should be attached to the syringe prior to drawing the reagent fluid. You will want to draw the plunger to the 1mL mark, and the actual fluid will not actually be drawn into the syringe, but will just be drawn into the tip. This ensures more consistent dosing, and avoids fluid fouling the syringe portion.
Hope this helps!
While there are those that do not use the tip for drawing reagent, the manufacturer does specifically recommend using the tip for the best consistency and accuracy, and we recommend following their directions.
Have a great day!
