Product description

Summarize

The luminous source of COD sensor emits strong ultraviolet light, the working beam directly to the photoelectric element, and the reference beam shines on another photoelectric element, and the chemical oxygen demand is calculated by measuring the absorption of ultraviolet light in the sewage. The product automatically compensates for the influence of chroma, turbidity and suspended matter of the measured sample.

Peculiarity

 digital sensor, RS-485 output, MODBUS support;

 No reagent, no secondary pollution;

 can measure COD/TOC/BOD and other parameters;

 Automatically compensates for turbidity interference;
