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.

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.
This is the Bee's Knees. By Albert on 8/1/2017Albert would recommend this product to a friendI test Alkalinity every other day and when I start a new tank I will often test my tank water both before and after a water change as well as the WC water.. Doing an alk test so quickly is a god send. If you just got this thing and think its a little slower to use than you thought dont worry in about a week of use you'll be doing it at blistering speed.
Very accurate By Nicholas on 7/17/2017Nicholas would recommend this product to a friendWorth the money, a lot of other test kits are hard to read and take 3 times as long to get the result.
Does the job By Sponge bob on 5/5/2017Sponge bob would recommend this product to a friendWhen I purchased the unit it would not turn on , changed battery and still would not operate, called BRS and they sent a return label in 5 minuets, I got ready to ship and it was working.
So I kept it. Definitely a cost effective precision test unit at 50 bucks so don't expect lab grade hardware at hobby prices.
Great! By Brandon on 4/15/2017Brandon would recommend this product to a friendQuick and easy way to measure your alkalinity.
Ask a question
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!
