## Overview

The Hanna Instruments HI 782 25 Marine Nitrate High Range Checker Reagents provide 25 pre-measured, high purity reagent packets designed for fast and accurate nitrate testing in saltwater environments. Compatible with the HI782 Checker, these reagents use the Zinc reduction method to deliver precise nitrate concentration readings from 0.0 to 75.0 ppm, with each packet clearly marked for expiration and lot traceability.

## Description

Product 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 Directions Simply add the HI782-25 reagent package to the sample, the reaction will occur, and the HI782 will determine the concentration of the color that is produced.
