Online Residual Chlorine Analyzer is 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 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. 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 Residual Chlorine 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.

Rodent infestation has long been a major problem plaguing farmland. According to relevant statistical data, since the 1980s, the annual area affected by farmland rodent infestation in some regions has accounted for 20%-30% of the total area of food crops. The rodent density is generally 10%-20%, and...
Road Weather Sensors are automated ground-based meteorological observation devices. They emit electromagnetic waves in specific bands (such as laser or infrared light) or utilize optical imaging technology to detect the characteristics of atmospheric particles like precipitation, fog droplets, and d...
Visibility can be measured by visual observation, relying on manual inspection to estimate the visibility distance based on whether a certain reference object is visible. This method is simple and intuitive, but it is highly subjective and has poor standardization and objectivity.We recommend using...
