SDW016 Intelligent COD Sensor Introduction: SDW016 is an intelligent COD sensor based on the principle of deep ultraviolet (UVC) absorption method for determining organic matter in water and integrating variable optical path technology. It adopts RS485 communication interface and standard ModBus/RTU communication protocol. The SDW016 intelligent COD sensor can quickly (in seconds) measure water quality parameters such as COD, turbidity, and water temperature, and can be converted into parameters such as BOD, TOC, and permanganate index, reflecting real-time changes in water quality. Equipped with variable optical path technology, it can automatically change the range to adapt to the detection of different concentrations of water. The variable optical path function, combined with optical path difference algorithm, eliminates the influence of window fouling and increases the accuracy and reliability of measurement. characteristic: 1.
