Description
The HI-774-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Phosphate Ultra Low Range Checker® HC. These reagents follow the Ascorbic Acid Method in which the reaction between phosphate and reagents causes a blue tint in the sample. By simply adding the packet of HI-774-25 reagent to the sample, the reaction will take place and the HI-774 will determine the concentration from the colour that is produced. The results will be displayed in ppb of phosphate.
