Better than tritation test, only test kit I will use to check my Alkalinity

The hanna checker is awesome. In a few simple steps, you know exactly what your alkalinity is.

Reliable, spot on numbers and easy to use. Better than tritation test.

This Hanna checker allows you to measure alkalinity very quickly and easily. It can be made even easier/quicker if you have a 1 mL pipettor. The measurements are very reproducible (high precision), but accuracy is harder to determine. For example, I made up some Red Sea Pro salt mix at 1.025 SG and measured alk with Hanna checker and the Red Sea Pro Alk kit. The results from two measurements were:
Hanna: 4.50 and 4.52 meq/L
Red Sea: 4.15 and 4.15 meq/L
These are significant differences, but the Hanna Check is closer to the expected value of ~4.4-4.53 meq/L. Of course, there is no guessing the end titration point with the Checker either. I've retired the Red Sea kit.

I used to use the Salifert Alkalinity test & found it hard to read the color change accurately but ever since i switched to the hanna alkalinity tester it has become very easy to precisely determine the value. The test does take around the same time to complete as the Salifert kit but there is no comparison with the Hanna digital readout. Great Product!

No more worrying about test results. I am now confidant or my tank's alk levels. I like this meter even better than the phosphate checker, which I also highly recommend.

Digital is the way to go. One reagent to add and you get a very accurate result. Tested twice in a row to see if the number would change even by 1ppm but it was identical. Wish you could change it to dkh vs ppm. Makes me do one more conversion.

I love this thing. I have been using the Hanna Alk checker for five months now and I still love it. My old Alk test was hard to delineate between the colors. With the digital read out there are no more questions of the results. The process is easy and fast. It is well worth the investment.
