Online Salinometer

1.Online Salinometer product introduction

Online Salinometer is an analyzer that measures the electrical conductivity of a solution; the higher the concentration of ions in the solution, the higher the conductivity.ZS7 Online Salinometer is an instrument that can monitor the conductivity of water quality online.It integrates water quality conductivity sensor and measurement module communication storage, and can quickly and accurately record key parameters in the water body.At the same time, the instrument supports extended water quality multi-parameter sensors, including but not limited to conductivity, pH, dissolved oxygen (DO), turbidity, temperature, ammonia nitrogen, etc., which can be combined and configured according to different needs and applications, and record and store history Monitoring data and alarm history records 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 Online Salinometer

Online multi-parameter water quality detectors are 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 adjust 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.

3.Technical features of Online Salinometer
