SPAS(Sulfur Auto System) ship pollutant discharge monitor is a high-performance online monitoring equipment developed and produced by LANScientific based on years of experience in atmospheric environment monitoring and combined with sensor technology at home and abroad. Choose electrochemical, optical and other high-precision sensors, mainly monitor the sulfur content in the air, temperature, humidity, wind speed, wind direction and other factors.
Based on wireless communication technology, the instrument collects environmental big data into the "cloud platform", combines the application of informationized big data to realize the functions of pollution source tracking, early warning and forecast, and provides timely and effective decision support for the monitoring and supervision of ship air pollution emissions.
