Hanna® Instruments Ultra High Range Chlorine Reagents HI95771-03

The Hanna Instruments HI95771-03 is a set of pre-measured reagents designed for the determination of ultra-high range chlorine levels (0-500 mg/L) using the HI96771 portable photometer. These high-purity, pre-made reagent packets simplify the testing process and ensure consistent, accurate results for up to 300 tests. Each packet comes with a traceable lot number and expiration date for quality control. When added to water samples, these reagents react with chlorine to produce a color change that is measured by the photometer, allowing for the determination of chlorine concentration in mg/L (ppm).
