With the Hanna Calcium Colorimeter Checker, you won't have to worry about the subjectivity of color charts. The Hanna colorimeter eliminates the effort of matching to a color chart by delivering a direct copper result digitally.
The Hanna Calcium Colorimeter Checker uses a 100 to 1 dilution for analysis and thus requires deionized or distilled water absent of calcium to function correctly. Calcium can be found in many freshwater sources and this any amount present in the water used at the C1 phase can cause false high readings. In addition, many hobby grade reverse osmosis deionized water systems may not adequately remove calcium. This can vary based on the types of filters used, their effectiveness and frequency of replacement. We recommend using deionized water with low conductivity or pure vapor distilled water commonly found in most pharmacies.
It comes with the reagent. You can buy more Hanna Calcium Colorimeter Checker Reagent.
