I. Application Areas
This product is suitable for monitoring water quality in environmental protection, water conservancy, municipal administration, enterprises, and other fields, including rivers, lakes, surface water, sewage treatment plants, sewage discharge outlets, process control, rural sewage, urban landscape rivers, municipal pipe networks, and other watersheds.
Recommended installation methods: submersible, buoy installation, and shore-based stations.
II. Working Principle
UV254 COD utilizes advanced deep ultraviolet UV LED cold light sources, which have a long lifespan and minimal drift. It employs internationally recognized, proven, and highly accurate ultraviolet absorption methods. No sample pretreatment is required, and the reaction analysis is fast, without the need for any reagents or sampling equipment. The sensor features mechanical self-cleaning functionality and uses a 400-880nm four-light-path compensation light source to effectively eliminate the impact of turbidity and chromaticity on measurements.
