1.Online COD Analyzer Product Introduction

Online COD Analyzer is an online water COD detector developed for low concentration COD (chemical oxygen demand) measurement needs.ZS1SOnline COD Analyzer is an instrument capable of online monitoring of water quality COD. It integrates water quality cod 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 the expansion of water quality multi-parameter sensors, including but not limited to cod, ORP, pH value, dissolved oxygen (DO), conductivity, turbidity, ammonia nitrogen, temperature, 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. Online COD Analyzer Application Areas

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 areas:

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 groundwater parameters such as pH, conductivity, and temperature in order to promptly detect and resolve water quality problems.

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. 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 COD Analyzer

1. High reliability: suitable for long-term work in the field environment, stable measurement and strong anti-interference ability.

2. Flexible and portable: Each probe can be freely combined, replaced independently, and plug and play.

3. Scalability: Various sensors can be freely combined.

4. Multiple applications: on-site rapid measurement, emergency monitoring, or long-term online monitoring of groundwater, river water, lake water, and urban pipe network water.

5. Tough shell: ABS+PC material, corrosion-resistant, can work normally for a long time.

6. Compact structure: can be installed in small places.

7. Communication connection: RS485 expansion interface, master/slave interface isolation and independent communication.
