Hanna HI719-25 Magnesium Hardness Checker Reagents – 25 Tests
The Hanna HI719-25 is a set of 25 high-quality, pre-measured reagents designed specifically for use with the HI719 Magnesium Hardness Checker. These reagents utilize the colorimetric method, in which magnesium ions react with the reagent to produce a violet-colored complex. The Checker HC then measures the intensity of the color and displays the result in ppm of magnesium hardness as CaCO₃.
Features
