RS485 Sewage Treatment Water Quality Monitoring Detector Cod analyzer price Online cod meter price Cod bod analyzer



Sewage treatment plants can use self-cleaning COD sensors to measure chemical oxygen demand (COD). Desun Uniwll online COD sensor combines many years of experience in the application of water quality sensors and has carried out a number of upgrades on the original basis. It adopts the RS485 communication interface and Modbus RTU standard protocol and has temperature and turbidity compensation functions. It is more convenient to install and has higher reliability.


The optical method online COD sensor (Chemical oxygen demand sensor) is more economical and environmentally friendly than the traditional chemical method. Small in size, easy to install, and can be used for continuous online water quality monitoring. Automatic compensation for turbidity disturbances, with automatic cleaning device, optional titanium alloy (corrosion resistant).


COD sensors are mainly used for monitoring rivers, lakes, sewage, and other types of surface water, etc., and can be easily integrated into water quality monitoring systems to meet customer needs.




* Digital sensor, RS-485 output, support MODBUS

* No reagents, no pollution, more economical and environmentally friendly
* Can measure SAC, COD, TOC, and other parameters
* Automatic compensation for turbidity interference for excellent test performance
