ZWQ-COD1 COD Sensor can be used to detect the Chemical Oxygen Demand value of water quality. It can be used in harsh environment and the monitoring data is stable and reliable.
ZWQ-COD1 is a COD intelligent sensor using RS485 communication interface and Modbus RTU standard protocol. COD is measured by 254 nm laser beam and turbidity is compensated by 546 nm laser beam. COD and turbidity can be measured simultaneously.

What is A COD Sensor?
A cod sensor which could measure Chemical Oxygen Demand in water. Mainly use the principle of Ultraviolet Absorption.
What does Chemical Oxygen Demand indicate?
The chemical oxygen demand (COD) indicates the amount of oxygen which is needed for the oxidation of all organic substances in water and is thus an important indicator for water analysis.
Why is Chemical Oxygen Demand important?
Chemical Oxygen Demand is an important water quality parameter because, similar to BOD, it provides an index to assess the effect discharged wastewater will have on the receiving environment.
What is chemical oxygen demand in water?
The chemical oxygen demand (COD) is a measure of water and wastewater quality. The COD test is often used to monitor water treatment plant efficiency.
What is meant by chemical oxygen demand?
COD or Chemical Oxygen Demand definition. … Chemical oxygen demand (COD) is a measure of the capacity of water to consume oxygen during the decomposition of organic matter and the oxidation of inorganic chemicals such as Ammonia and nitrite.
