- 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 HI755-26 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
Designed to work with HANNA's liquid reagents. Uses 10 mL glass cuvettes.

Extremely useful alk tester By David on 1/17/2018David would recommend this product to a friendJust as expected from Hanna, this is an easy to use, accurate testing equipment that takes all the guess work out of differentiating between shades of color.
Couldn't be faster or easier! By Noel on 1/9/2018Noel would recommend this product to a friendThis is an indispensable part of my testing arsenal. It's so quick, easy, and reliable. I only wish chemistry allowed the other checkers to be this simple. I could not go back to a titration test kit for Alkalinity after using this.
Quick and Easy By John on 11/28/2017John would recommend this product to a friendBy far the easiest tester you'll use. Very accurate. Reagent is easy to use and cheap.
Works great By Matt on 11/23/2017Matt would recommend this product to a friendI’ve had for 6 months. Works great. Easy to use.
do not waste your money By chris on 11/1/2017chris wouldn't recommend this product to a friendProduct works great for 1 year and 4 months then the button breaks. I was very careful and gentle with the instrument. I contacted BRS and they say its our of warranty. I contacted Hanna and they say the same. This product should last longer.
Good Product By Ksf1 on 10/31/2017Ksf1 would recommend this product to a friendI've sed the Hanna Checker for phosphates for years, but continued to use a Salifert test kit for Alkanity. This is a huge improvement. Not that the Salifert kit was bad, but difficult to confirm consistency using the color chart and possible errorts in the drip test.
Well Worth It By Xxero on 10/20/2017Xxero would recommend this product to a friendEasy instructions. After you run the test a couple of times, the whole process only takes minutes. 100% happy with this product!
Love It By Zotch on 9/22/2017Zotch would recommend this product to a friendQuick accurate reading and simple to use. Video is very helpful..Randy is the man.
Very easy to use By Bakerrichard27 on 9/1/2017Bakerrichard27 would recommend this product to a friendI absolutely love it no more color guessing very smooth easy operation and extremely accurate
Fast and easy By GP on 8/29/2017GP would recommend this product to a friendVery easy to use and gets fast results.
Easy Alkalinity testing By john on 8/21/2017john would recommend this product to a friendI love the digital result verses the color change result. The test is easy and very quick. I won't go back to titration method tests.
Makes checking Alkalinity easy! By Phil on 8/8/2017Phil would recommend this product to a friendThis meter makes checking Alkalinity very easy. I used to dread testing, but now it's actually a pleasure to do. I will never go back to the old count the drops system.

The dKH checker by Hanna is one if the easiest to use and just as accurate as all current hobby grade test kits for dKH currently available. Feel free to let us know if you have any further questions!
This checker includes 25 tests. If you have any other questions, let us know!
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!
This checker will use the same reagent as the HI755-26. Feel free to let us know if you have any further questions!
