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

Easy to use but didn't last! By Pierre on 2/11/2017Pierre would recommend this product to a friendFirst, it is really easy and fast to use, seems accurate enough for the average Joe. I had mine for 8 months and it stopped working. (Error L.HI)
I contacted Hannah support by email and got a reply within a few hours (Great!) Unfortunately, the warranty is 6 months only and because of the price range, there's no repair or return possible.
Overall, great little tester, but it might not last!
Some piece of advice:
Store in a dry area, make sure no water ever touch it. Be sure you wipe any excess of water from the sample tube before insertion. Wipe again...and wipe...It will help for accuracy and longevity!

Colorblind Perfect! By Nick on 1/10/2017Nick would recommend this product to a friendSo being shade blind it is hard for me to determine the proper levels in my tank. I usually just guess about and or around. But just ordered this Hanna Alk tester and right on point. Can't wait to get the other testers. Cost little bit more but well worth it because i'm not guessing anymore when checking my levels.!

Great product By Mitch on 12/19/2016Mitch would recommend this product to a friendWorks as stated. Removes the guess work from testing Alk.
Much more accurate By Brad on 12/16/2016Brad would recommend this product to a friendUsing a 6.7 dKH standard, the Hanna read exactly 6.7 dKH. My display tank read 9.3 dKH on the Hanna whereas my Salifert kit showed 10.0 dKH. Will be switching to Hanna for Calcium testing soon.
Fast, accurate,easy to use. By mac on 12/10/2016mac would recommend this product to a friendTried the expensive 10 step computer type testers that send all the records to my computer and after many attempts. found them way to confusing for my simple brain..

great product By Jennifer on 11/4/2016Jennifer would recommend this product to a friendEase of use and cost per test make this product one of my favs. I recommend getting the controls so you can make sure to know if your unit is reading spot on or up or down a bit. then just make adjustments to final reading to make sure it is within proper range.
