ORP vs. Colorimetric Monitoring – What’s the Difference? When measuring water quality, accuracy matters. But did you know that ORP sensors don’t always give the full picture? Here’s why: 💧 ORP (Oxidation-Reduction Potential) measures overall water chemistry, but its readings can be affected by factors like pH, temperature, and chlorine concentration. That means changes in one parameter can throw off your results. 🎯 Colorimetric technology works differently. Instead of measuring overall chemist
