The HI781-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their HI781 Marine Nitrate Low Range Colorimeter. These reagents follow a colorimetric method in which the reaction between nitrate and the reagent causes a pink/violet tint in the sample. This checker has been developed to work with seawater samples.
