This tester is super easy to use and results are fast and accurate. I have always had a hard time trying to compare colors on other test kits, the Hanna Checkers take all of the guesswork out of it and give you an actual number.
hands down the best alk tester on market By BK on 2/6/2013

Love this test kit for its simplicity and digital readout. You must do a simple calculation to get DKH reading (multiply X 0.056) and then you are set. Used red sea alk before but always had some gray areas with the titration.

I have both the Hanna Alkalinity and Phosphate checkers. Both are incredibly easy to use and the results are very accurate. I would recommend them to anyone looking for better test results. The initial investment for the checker is well worth it as the refill kits are cheaper than buying test kits repeatedly.
Great Product! By Bobby on 1/20/2013

It works just like its suppose to. It's very easy to use and is all organized in a waterproof case. Hope to see more quality products like this one for the aquarium hobby.

This is almost perfect, except for the fact that the actual results need adjusting (see Randy's AA article). Super easy to use and fast. No guessing color changes. Once you have your adjustment factor dialed in, results are very consistent.
Easy to use with consistent readings, but... By jlemoine2 on 10/24/2012

I've used the Hanna Alk checker for about year now, I'm on my 4th bottle of reagent, so I love using this test kit. The instructions are clear and testing water samples is a simple process. Doing tests one after the other shows consistent results, making almost dummy proof.
Advanced Aquarist magazine did a review of this checker against an EPA approved testing device. They found the Hanna checker to give results that were too high.. but at least the high reading was consistently higher at various concentrations of Alkalinity.
After learning this kit measured high, I compared it to a Salifert Alk test kit. The Salifert kit confirmed the articles conclusion. My reading was higher on the Hanna meter. In my case, I was a little bit low on my Alk and needed to raise it a bit.
After a couple of months testing with both the Hanna meter and Salifert kit, I noticed the Hanna meter reads a consistent 0.7 to 0.9 dKH higher than the Salifert kit. If you are riding on the low end of the Alk scale, that could be significant.
Now that I know there the Hanna kit reads high, I no longer use the Salifert kit, as I'm looking for consistency in the Alk kit, and the Hanna meter more than capable of detecting the rise and fall in levels in order to adjust my 2-part dosing.
I recommend the Hanna kit over the Salifert kit simply because it's easy to use and consistent. I hate the drip-and-swirl and watch for color changes that come with other kits... but the other kits make sense for "sanity checks".
