## Overview

The Hanna Instruments HI774-25 reagent packets provide 25 pre-measured ultra low range phosphate tests, using high purity chemicals and the Ascorbic Acid Method for precise detection between 0.00 and 0.90 ppm. Each packet is clearly marked with expiration and lot numbers, ensuring traceability and reliability when used with the HI774 Phosphate Ultra Low Range Checker HC.

## Description

The HI774-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Phosphate Ultra Low Range Checker HC. These reagents follow the Ascorbic Acid Method in which the reaction between phosphorus and reagents causes a blue tint in the sample. By simply adding the packet of HI774-25 reagent to the sample, the reaction will take place and the HI774 will determine the concentration from the color that is produced. The results will be displayed in ppb of phosphorus. These reagents are designed to be used with samples that have an expected range of 0.00 to 0.90 ppm phosphate.FEATURESPre-made reagents for ease of usePrepared with high purity chemicalsMarked with expiration date and lot number for traceability
