water quality sensor

1.Water quality sensor product introduction

water quality sensor is used to measure common water treatment parameters, such as dissolved oxygen, conductivity, turbidity, pH, temperature, ammonium, nitrate, chloride, etc.Online water quality sensorZS07 is an instrument that can measure multiple water quality parameters simultaneously.It integrates a variety of sensors and measurement module communication storage, and can quickly and accurately record multiple key parameters in the water body.Including but not limited to water temperature, conductivity, PH, dissolved oxygen, ammonia nitrogen, COD, turbidity, etc., can be combined and configured according to different needs and applications, record and store historical monitoring data, alarm history, and support historical data export.xlsx.The RS485 interface supports the MODBUS-RTU communication protocol to facilitate users to freely communicate with PLC, DCS, configuration software, DTU and other equipment to connect and transmit data.

2.Application fields of water quality sensor

ZS07 online water quality sensor is widely used in the monitoring and control of various water bodies, including but not limited to the following fields:

1.Water plant: used to monitor the pH value, dissolved oxygen, turbidity and other parameters of tap water to ensure the safety and hygiene of tap water.

2.Groundwater monitoring: used to monitor the pH value, conductivity, temperature and other parameters of groundwater to detect and solve water quality problems in a timely manner.

3.River and lake monitoring: used to monitor the water quality conditions of rivers and lakes, such as dissolved oxygen, turbidity, ammonia nitrogen and other parameters, so as to take timely pollution control measures.

4.Marine monitoring: used to monitor the water quality conditions of the ocean, such as salinity, dissolved oxygen, temperature and other parameters, so as to detect and control marine pollution in a timely manner.

5.Sewage treatment: used to monitor the water quality parameters of sewage, such as pH value, COD, ammonia nitrogen, etc., in order to control and regulate the sewage treatment process.

6.Industrial production: Used to monitor water quality conditions during industrial production, such as pH, conductivity, dissolved oxygen and other parameters, so as to adjust the process in a timely manner and ensure product quality.

7.Scientific research: used for water quality monitoring in the field of scientific research, such as lake eutrophication, climate change, etc.
