Online COD BOD Sensor Waste Water Treatment RS485 Chemical Oxygen Demand COD BOD Tester



Online COD BOD TSS analyzers are devices used to monitor and measure the levels of organic matter and suspended solids in wastewater. COD stands for Chemical Oxygen Demand, BOD stands for Biological Oxygen Demand, and TSS stands for Total Suspended Solids. These three parameters are important indicators of the quality of wastewater and are used to ensure that the water is safe to discharge into the environment.


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
