Reagents Marine Calcium (saltwater) for 25 Tests The HI758-26 are the replacement reagents for the HI758 Marine Calcium Checker® HC.  Pre-made reagents for ease of use Prepared with high purity chemicals Marked with expiration date and lot number for traceability The HI758-26 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Marine Calcium Checker® HC. These reagents follow the Zincon Method in which the reaction causes a blue tint in the sample. By simply adding 1 mL of the first reagent to the sample, followed by a packet of the second reagent in the HI758-26 set, the reaction will take place and the HI758 will determine the concentration from the color that is produced. The results will be displayed in ppm of calcium. These reagents are designed to be used with samples that have an expected range of 200 to 600 ppm calcium.
