1. Water Hardness Tester Product Introduction

Water Hardness Tester is used to measure the total hardness of water quality, used to monitor the hardness of softened water, groundwater and other water quality.GL02 Online Water Hardness Tester is an instrument that can monitor the total hardness and chloride ion of water quality online. It integrates water hardness sensor, chloride ion sensor and measurement module communication storage, 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, including but not limited to pH value, dissolved oxygen (DO), conductivity, turbidity, temperature, ammonia nitrogen, etc., which can be combined and configured according to different needs and applications, record and store historical monitoring data, alarm history records, and support historical data export.xlsx. The RS485 interface supports MODBUS-RTU communication protocol to facilitate users to communicate freely with PLC, DCS, configuration software, DTU and other devices to connect and transmit data.

2. Application fields of Water Hardness Tester

Online Water Hardness Tester is widely used in monitoring and controlling various water bodies, including but not limited to the following areas:

1. Factory boiler water quality monitoring: used to prevent the formation of scale, prevent equipment corrosion, and ensure equipment safety.

2. Groundwater monitoring: used to monitor groundwater parameters such as pH value, conductivity, temperature, etc., so as to detect and solve water quality problems in time.

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

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

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

6. Industrial production: used to monitor water quality in industrial production processes, such as pH, conductivity, dissolved oxygen and other parameters, so as to adjust the process in time and ensure product quality.

7. 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.

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