Measuring Principle
Online COD sensor is based on the absorption of ultraviolet light by organic matter, and uses the 254 nm spectral absorption coefficient SAC254 to reflect the important measurement parameters of soluble organic matter content in water, and can be converted into COD value under certain conditions. This method allows for continuous monitoring without the need for any reagents.
Main Features
1) Directly immersion measurement without sampling and pre-processing
2) No chemical reagents, no secondary pollution
3) Quickly response time and continuous measurement
4) With automatic cleaning function and few-maintenance
Application
1) Continuous monitoring of organic matter load in the sewage treatment process
2) On-line real-time monitoring of influent and outflow water of the wastewater treatment
3) Application:surface water, industrial discharge water, and fishery discharge water etc
