Get A QuoteThe FST100-COD106 Chemical Oxygen Demand (COD) Sensor provides fast, accurate, and continuous measurement of dissolved organic contaminants in water using advanced ultraviolet absorption technology. By detecting UV absorption at 254 nm and combining it with a reference light source for turbidity measurement, the sensor effectively minimizes interference from suspended particles through intelligent compensation algorithms.
Its reagent-free measurement technology eliminates chemical consumption and secondary pollution while reducing operating costs. The integrated cleaning brush helps prevent biological fouling, ensuring reliable long-term performance with minimal maintenance. Featuring a durable 316L stainless steel housing, IP68 protection, and RS485 Modbus/RTU communication, the sensor integrates easily into modern water quality monitoring systems for industrial and environmental applications.
