Water Quality COD BOD detector- COD/BOD sensor

About – Water COD BOD Meter

COD: Chemical Oxygen Demand COD is a chemical method to measure the amount of reducing substances that need to be oxidized in a water sample. Oxygen equivalent of substances (generally organic substances) that can be oxidized by strong oxidants in wastewater, wastewater treatment plant effluent and polluted water. In the study of river pollution and the nature of industrial wastewater and the operation and management of wastewater treatment plants, it is an important and fast-determinable organic pollution parameter, often represented by the symbol COD.


BOD: Biological Oxygen Demand BOD refers to the amount of dissolved oxygen consumed in the process of decomposing organic matter in the water body into inorganic matter by aerobic microorganisms, referred to as BOD. The size of this indicator indirectly reflects the amount of organic pollutants in the water body, and is an important indicator of the degree of pollution in the water body

COD detector

Optical method online COD sensor is more economical and environmentally friendly than 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).


Optical detection, high efficiency.

Automatic cleaning to reduce the impact of contaminants.

Can measure parameters such as SAC/COD/TOC.

Automatic compensation for turbidity disturbances.

BOD Water Quality Sensor

The tryptophan in the water is excited by ultraviolet light to produce fluorescence. The detector detects this fluorescence signal and the sensor’s built-in correction parameters convert the tryptophan fluorescence signal into related biochemical oxygen demand, using tryptophan indirectly By measuring BOD, the BOD value of water quality can be obtained.


The Water quality BOD/COD analyzer can be applied to sewage treatment plant/surface water of rivers/aquaculture/biomedicine/industrial production industrial wastewater/urban sewage/domestic sewage/surface water of rivers, etc.
