Note

1.) The COD and TOC value can be measured directly.

2.) BOD data calculated base on measured COD data through the conversion factor. (Conversion factormodel need be build by end user and need used togetherwith our controller.)

3. ) COD sensor with turbidity compensation: The measured turbidity value which is mainly used to compensate for COD measurement, and the turbidity value not recommended to be used as measurement data directly
