The HI772 Checker®HC (Handheld Colorimeter) provides a simple, accurate, and cost-effective way to measure alkalinity in degrees of carbonate hardness, commonly abbreviated as dKH. Critical to marine environments, alkalinity not only provides the carbonate ion required for calcium carbonate skeletal regeneration of coral reefs, but it also acts as a pH buffer against large changes in acidity. Designed as a more accurate alternative to chemical test kits, the HI772 provides quick, accurate results in a few easy steps.

Everybody should have One
This was my first Hanna Checker, I was using Red Sea.
This is easy to use, gives good results. No guessing when the color changed, especially if doing your testing in the evening when it's darker. I put the test vials into the checker the same way every time. Typically where the break is located in the "fill to" line. Put that towards me, make sure that it's clean. I haven't had the need to use fancy glass cleaners/ lens cleaners, just a paper towel if there are visible fingerprints. then Bam, you get your results. No guessing.
