Hanna Instruments HI774-25 Phosphate Ultra Low Range Checker HC Reagents (2 Set - 50 Tests.

The HI77425 are highquality reagents that are premeasured, 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 HI77425 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.
