Marine Nitrate High Range Checker Reagents

Hanna Marine Nitrate High Range Checker Reagents are replacement reagents for the Hanna Saltwater Nitrate Checker HC - High Range. These pre-measured reagents are prepared with high purity chemicals and use the Zinc reduction method in which the reaction between nitrate and the reagent causes a pink tint in the sample. The results will be simply displayed in ppm of nitrate (as NO3-). These high quality reagents are designed to be used with saltwater samples that have an expected range of 0.0 to 75.0 ppm. Comes with 25 tests.
