## Overview

The Hanna Instruments HI 782-25 offers 25 pre-measured, high-purity reagent tests designed for fast and accurate nitrate measurement in saltwater aquariums. Utilizing the zinc reduction method, it provides reliable ppm readings up to 75, with each packet traceable by expiration date and lot number, making it a must-have for professional and hobbyist marine aquarium managers.

## 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
