UV254 Absorption Method RS485 COD/TOC sensor for waste water treatment
UV fluorescence absorption COD sensor COD351L is a technology that uses the absorption and fluorescence characteristics of organic substances in samples to ultraviolet (UV) to measure chemical oxygen demand (COD).
This sensor uses the ultraviolet fluorescence properties of organic substances in a sample to measure chemical oxygen demand (COD). COD is an indicator of the concentration of organic pollutants in water, which represents the amount of organic matter in water that needs to be oxidized with oxygen, thereby evaluating the degree of pollution of the water body. The advantages of UV fluorescence absorption COD sensors include rapid analysis, no reagents, real-time monitoring capability, and high sensitivity to low concentrations of organic substances. It is often used in water treatment plants, environmental monitoring, industrial process control and other fields.
