Cod online monitoring equipment: Long term monitoring of COD trends and prediction of eutrophication risks in water bodies. [Model recommendation: TH-ZS1S, IoT integrated device, customized service supported by Yunjing Tianhe] COD online monitoring equipment can effectively evaluate the degree of organic pollution in water bodies by real-time and continuous monitoring of the trend of chemical oxygen demand (COD) changes in water bodies, combined with data analysis and model prediction, providing scientific basis for predicting eutrophication risks in water bodies. It is a key tool for water quality management. Built in large capacity storage module, records historical data (including time, COD value, temperature, pH, etc.), supports data query, statistical analysis, and trend prediction, providing long-term data support for water quality management. The device can set a monitoring frequency (such as once per minute), continuously collect water sample data, generate COD concentration change curves, and capture dynamic fluctuations in water quality. Through IoT technologies such as 4G/5G, LoRa, RS485, monitoring data is transmitted in real-time to remote monitoring centers or mobile terminals, supporting remote calibration, parameter settings, and equipment status diagnosis to improve management efficiency.

1、 Product Introduction

Online water quality analyzer is an instrument that can monitor water quality COD online, and can quickly and accurately record key parameters in water bodies. At the same time, the instrument supports the expansion of water quality multi parameter sensors, which can be combined and configured according to different needs and applications, record and store historical monitoring data and alarm history records, and support the export of historical data. The RS485 interface supports the MODBUS-RTU communication protocol, making it convenient for users to communicate freely. It can connect and transmit data with devices such as PLC, DCS, configuration software, DTU, etc.
