Hanna Instruments Hanna Checker Colorimeter


To earn the BRS Recommended badge of approval the aquarium product must offer great value at its particular price or accomplish something truly unique for your aquarium. In many cases, it is a combination of both that brings these products to the forefront and worthy of highlighting.


The Hanna Checker Alkalinity dKH Colorimeter nails it providing the best value among alkalinity test kits. Nothing we have tested is as easy, quick and reliable as the alkalinity checker.


Hanna Checker digital read out


If you don’t like reading color changes or unsure about the exact end point of said color changes, the digital readout provided by the Hanna dKH checker means you no longer have to do that. In addition to eliminating this point of common human error, there is something about seeing an actual number that just instills confidence.


Here at BRS, we use the Hanna Instruments alk checkers on dozens of tanks because it is easy and reliable. We know that no matter who performs the test, we can expect very consistent results.


BRStv Investigates Hanna Alk Checker Results


In a recent BRS Investigates episode we had 5 different people use the checker and the variance among the results was only 0.3 dKH. That was 2-5 times better than any other alkalinity test kit we used during that experiment.


In terms of ease of use, it requires 3 very straightforward steps to get your readings and leaves very little room for screwing it up. Simply zero the unit with your sample, add the reagent, and then take your reading.
