In stock

The HI774-25 are the replacement reagents for the HI774 Phosphate Ultra Low Range Checker® HC. These high-quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.

  • Pre-made reagents for ease of use
  • Prepared with high-purity chemicals
  • Marked with expiration date and lot number for traceability


The HI774-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Phosphorus 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 ppm of phosphate. These reagents are designed to be used with samples that have an expected range of 0 to 0.90 ppm phosphate.
