## Overview

The Hanna Instruments HI782-25 reagent packets provide 25 pre-measured, high-purity chemical tests designed for accurate nitrate measurement in marine and brackish water. Compatible with the Marine Nitrate High Range Checker HC, these reagents use the Zinc reduction method to deliver fast, reliable ppm nitrate readings from 0 to 75, with full traceability via expiration and lot numbers.

## 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
