Oxidizing antimicrobials, such as chlorine, are common disinfectants used to treat water. Test strips, DPD kits, and colorimeters are currently the most popular methods for determining the relative disinfecting power of oxidizing antimicrobial agents in these applications. Unfortunately, these testing options often target narrowly specific sets of chemicals and chemical reactions that may have little to do with the actual chemistry of your water or disinfectant method.

This article explains how ORP measurement works and why an ORP-based test method is a flexible and effective alternative for determining disinfectant power of oxidizing antimicrobial agents in aqueous solutions.
