Digital COD controller, also called digital COD transmitter, is a device specially designed to test and control the chemical oxygen demand (COD) level. It receives data from the COD sensor and uses the built-in software algorithm to intelligently adjust various parameters in the detection process to ensure the accuracy and reliability of the detection results.

 

The working principle of the digital COD controller mainly relies on the ultraviolet UV absorption method. Specifically, it uses the COD sensor to measure the absorbance of sewage at a wavelength of 254nm, and accurately converts the COD concentration value through the established relationship between absorbance and COD concentration. This method not only does not require the use of any reagents and avoids secondary pollution, but also has low cost of use, simple operation and maintenance, low failure rate, and short testing time.

 

Compatibility: The digital COD controller is compatible with all Daruifuno brand digital COD sensors, which is convenient for users to select and replace.

Multi-parameter display: In addition to displaying COD parameters, it can also display parameters such as TOC, TU and BOD to provide users with comprehensive water quality information.

Data recording function: It has time and historical data recording functions, which is convenient for users to view and analyze water quality changes at any time.

Large screen display: It uses a 3.2-inch large LCD screen with clear display, which is convenient for users to read data.

User-friendly interface: It provides an English interface, which is simple and intuitive to operate and convenient for users to use.

Password protection: It supports setting passwords to prevent misoperation and ensure data security.

Multiple installation methods: It supports multiple installation methods, which is convenient for users to flexibly configure according to actual needs.

 

The digital COD controller has a wide range of application value in water quality monitoring, environmental assessment, industrial wastewater treatment and other fields. It can quickly and accurately measure the organic matter content in water, which is one of the important comprehensive indicators for evaluating the degree of water pollution. By real-time monitoring and analysis of water quality data, the digital COD controller provides strong support for water quality monitoring and management.

 

In summary, the digital COD controller is an efficient, accurate and convenient water quality monitoring equipment, which plays a vital role in the field of water quality monitoring.
