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

Awesome By RussC on 3/5/2018RussC would recommend this product to a friendLove it. Much simpler than color testing. Easy, fast and spot on. Consistent every time. Even when doing multiple tests back to back.
Good but came broken By Lukey on 2/26/2018Lukey would recommend this product to a friendThe product is good overall but the syringe it comes with came broken.
Worth Every Penny By Mike on 2/24/2018Mike would recommend this product to a friendLet me just say, this Hanna Checker is worth its weight in gold. From testing being under 2 minutes from start to finish, to the reliable accuracy, and ease of reading the results, this checker has helped me dial in my dosing amounts for my reef and in turn has left me with a very stable Reef Tank with tons of Growth. Id definitely recommend this if youre looking for a quick and easy way to test alkalinity (a.k.a. one of the most important parameters to be kept stable in a reef).
Best investment ever!!!! By Jason on 2/23/2018Jason would recommend this product to a friendThis is simple to use and accurate compared to the salifert kit, I compared them to the ALK salifert and it was off by 6. Very happy with this, get it now don't hesitate!
Hanna Checker By Popo1980 on 2/19/2018Popo1980 would recommend this product to a friendThis is a friendly test and really easy, the most important is the accuracy of the test.
Excellent reliability By Tautog on 2/8/2018Tautog would recommend this product to a friendI have Excellent Reliability and trust in the Hanna Alkalinity dKH meter!
I have, and do regularly compare results to Rea Sea. Consistently testing correctly is key to any test kit, but cleaning these glass cylinders with hot water to prevent staining, and allowing them to dry completely, will help give better results. Thus, having a routine for each test, makes you a better chemist!
Time saver By Justin on 1/23/2018Justin would recommend this product to a friendJust buy it, you’re wasting your time otherwise. ATI provides vague whole number results and Red Sea is more time consuming and approximately as accurate. This makes me feel so much more in tune with my growing reef,
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.

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!
