UV254 Sensors for Real-Time Organic Matter Detection in Water

UV254 sensors are critical tools for measuring organic matter in water by analyzing UV light absorption at the 254 nm wavelength. This parameter is directly linked to water quality indicators such as Chemical Oxygen Demand (COD) and Total Organic Carbon (TOC). These sensors enable continuous, real-time monitoring without the need for reagents, making them invaluable in municipal water treatment, industrial discharge, and environmental compliance applications.UV254 technology supports proactive decision-making and enhances operational efficiency. From wastewater plants to drinking water facilities, these sensors offer actionable insights for early detection of contamination and treatment optimization.Water Quality Instruments is a leading B2B company serving North America with smart, reliable, and scalable water monitoring solutions.
