HI-775-26 Reagents For Freshwater Alkalinity Checker HI-775 (25 tests)

The HI-775-26 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Freshwater Alkalinity Checker® HC. These reagents follow the Colorimetric Method in which the reaction causes a distinctive range of colours from yellow to green to blue to develop. By simply adding one drop of the Chlorine Remover to remove the chlorine interference, and subsequently adding 1 mL of the Alkalinity Reagent to the sample, the reaction will take place and the HI-775 will determine the concentration from the colour that is produced. The results will be displayed in ppm of CaCO₃. These reagents are designed to be used with samples that have an expected range of 0 to 500 ppm CaCO₃.
