COD sensor that can automatically be perpendicular to the water

Introduction of 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 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, as well as the operation and management of wastewater treatment plants. It is an important and fast-determinable organic pollution parameter.

COD sensor that can automatically be perpendicular to the water:

The COD sensor can always remain vertical in the water. It can ensure the accuracy of data measurement, and the product line can choose one built-in steel wire mesh material. A common material, the core of the product is made of high-precision copper. The outer skin is flexible and resistant to bending, tensile and abrasion resistance. Not only the measurement data is accurate, the output signal is stable, and the accuracy is high. It has a wide measurement range, high stability, convenient use, easy installation, and long transmission distance. In addition, the turbidity compensation function can automatically compensate the turbidity in the water. It is a sewage cod online detector.

The water quality sensor adopts spectrophotometry to detect. The main detection principle is that organic matter has the maximum absorption value in the ultraviolet region of 254nm. Suspended matter absorbs visible light at 900 nm, while the absorption of organic matter is almost zero. The COD value of water quality can be obtained by measuring the degree of absorption of the twopaths of light.

The importance of water quality COD testing:

Facing the shortage of freshwater resources, it is important to strengthen the protection and rational use of water resources. The treatment of wastewater produced in production and life and discharge after reaching the standard has become an important link in water environmental protection. COD is an important detection indicator, and sewage monitoring equipment can provide support for the discharge of sewage and promote the rational use of water resources.
