This document describes a new methodology for testing chlorine levels poolside using DPD colorimetric testing with eXact® Strip Micro reagent delivery devices. The method involves using a waterproof chlorine test meter and eXact® test strips to quickly and easily measure free chlorine and total chlorine levels directly in pool water. The procedure takes about 2 minutes and provides accurate results to monitor chlorine levels and determine if the pool needs to be shocked to convert combined chlorine back to free chlorine. The method meets EPA and health department standards and provides a simple, reliable way for non-technical staff to test pool water quality poolside.
