Designed for aquariums, aquaculture, and environmental water quality monitoring, these compact reagents eliminate conversion steps and deliver lab-grade precision in a convenient format. ## Description The HI774-25 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 phosphorus and reagents causes a blue tint in the sample. By simply adding the packet of HI774-25 reagent to the sample, the reaction will take place and the HI774 will determine the concentration from the color that is produced. The results will be displayed in ppb of phosphorus. These reagents are designed to be used with samples that have an expected range of 0.00 to 0.90 ppm phosphate. Easier to use and more accurate than chemical test kits; Dedicated to a single parameter; Small size, big convenience; Ideal for: Aquariums, Environmental, Aquaculture, Water Quality.
