The digital online COD/BOD/TOC 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/BOD/TOC value under certain conditions. This method allows for continuous monitoring without the need for any reagents.
Technical 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
