Environmental On-line Monitor - Pollutant Discharge Monitor

Pollutant Discharge Monitor

Pollutant Discharge Monitor, drawing from years of experience in atmospheric environment monitoring and utilizing sensor technology from both domestic and international sources. It uses high-precision sensors such as electrochemical and optical sensors to primarily monitor sulfur content in the air, as well as temperature, humidity, wind speed, wind direction, and other factors.

Pollutant Discharge Monitor utilizing wireless communication technology, the instrument gathers environmental big data into a "cloud platform," integrating the application of informationized big data to track pollution sources, issue early warnings and forecasts, and provide timely and effective decision support for monitoring and supervising ship air pollution emissions.
