Hanna Instruments Hanna Alkalinity Pocket Checker dKH

Hanna offers two different alkalinity checkers for marine aquariums.  Both of the meters test with the same accuracy and the only difference would be your personal preference for the unit of measure.

The dKh version has a range from 0 – 20.0 dkH with a resolution of 0.1 dkH.  The ppm Version has can measure from 0 – 250ppm with a resolution of 0.1 ppm.  Both of them offer quick accurate test results and will help you to more accurately monitor the critical parameter of alkalinity inside your aquarium.

These Hanna Checkers can be a real life saver, so if you’re sick of hassling with liquid test kits and wants a quick and accurate way to test your alkalinity, the Hanna Instruments Alkalinity Colorimeters are a great choice.
