## Overview

The Hanna Instruments HI 782-25 reagent packs deliver 25 pre-measured, high purity chemical tests designed for accurate marine nitrate measurement up to 75 ppm NO3–. Each reagent is traceable with expiration and lot numbers, ensuring reliable, fast results with the Zinc reduction method for saltwater aquarium monitoring.

## Description

The HI782-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Marine Nitrate High Range Checker HC. These reagents follow the Zinc reduction method in which the reaction between nitrate and the reagent causes a pink tint in the sample. By simply adding the packet of HI782-25 reagent to the sample, the reaction will take place and the HI782 will determine the concentration from the color that is produced. The results will be displayed in ppm of nitrate (as NO3–). These reagents are designed to be used with saltwater samples that have an expected range of 0.0 to 75.0 ppm.FEATURESPre-made reagents for ease of usePrepared with high purity chemicalsMarked with expiration date and lot number for traceability
