Water, as the source of life, its quality is directly related to human health and the stability of the ecological environment. Water quality detection is a crucial means for water resource protection and pollution control, providing important data support for strict water resource management systems. Whether it is industrial water, drinking water, or the water treatment process, the water quality conditions have a decisive impact on life safety and product quality. The quality of water sources, as the source of domestic drinking water, if there are excessive heavy metals or pollution caused by human activities, long-term consumption will endanger human health.
There are various methods for water quality detection. Currently, physical and chemical monitoring technologies are mainly adopted, including chemical methods, electrochemical methods, atomic absorption spectrophotometry, etc. Among them, ion-selective electrode methods and chemical methods are widely used in routine water quality monitoring. In addition, biological monitoring uses the response of organisms to pollution to clarify the water quality conditions, and it has the characteristics of sensitivity, etc.; remote sensing monitoring technology can invert water quality parameters through spectral characteristics, and it can monitor water quality changes over a large range, quickly and at a low cost.
Online monitoring is a real-time and dynamic water quality monitoring method that can promptly reflect changes in water quality and provide a basis for taking timely measures. The Online Water Quality Analyzer FT-ZS can simultaneously measure key water quality parameters such as chemical oxygen demand (COD), turbidity, and temperature. Users do not need to rely on multiple devices; a single FT-ZS can comprehensively grasp water quality information. This instrument integrates the communication and storage functions of the water quality COD sensor and the measurement module, and can quickly and accurately record the key parameters of the water body. It also supports the expansion of multi-parameter water quality sensors, such as ORP, pH value, dissolved oxygen, conductivity, ammonia nitrogen, etc., and can be flexibly configured according to different needs. Moreover, it can record and store historical monitoring data and alarm historical records, and supports the export of historical data in.xlsx format. Through the RS485 interface, following the MODBUS - RTU communication protocol, it is convenient to connect and transmit data with devices such as PLC, DCS, configuration software, and DTU.
The Online Water Quality Analyzer is widely applied in multiple fields. In waterworks, it is used to monitor the pH value, dissolved oxygen, turbidity, etc. of tap water to ensure drinking water safety; in groundwater monitoring, it monitors parameters such as pH value and conductivity to promptly detect water quality problems; in the monitoring of rivers, lakes, and the ocean, it monitors dissolved oxygen, ammonia nitrogen, etc., contributing to pollution treatment and prevention and control; in sewage treatment, it monitors parameters such as pH value and COD to regulate the treatment process.
