GS+4SO2 Sulfur Dioxide (SO2) Sensor For Air Quality Monitoring Industrial Safety Automotive

Working Principle:

The GS+4SO2 sensor works based on the electrochemical three - electrode principle. Sulfur dioxide and oxygen undergo corresponding oxidation - reduction reactions on the working electrode and the counter - electrode respectively, and release charges to form a current. The magnitude of the current produced is proportional to the sulfur dioxide concentration. By measuring the current size, the level of sulfur dioxide concentration can be determined.

Key Features:

  • High stability, which ensures accurate and reliable measurement results over time.
  • Fast response and recovery, enabling quick detection and return to the baseline after the removal of the target gas.
  • Robust environmental stability, allowing it to work properly in various environmental conditions.

Common Applications:

  • Industrial safety, for detecting sulfur dioxide in industrial production processes to ensure the safety of workers and equipment.
  • Industrial general, such as in chemical plants and other industrial sites to monitor sulfur dioxide emissions.
  • Air quality monitoring, to detect the content of sulfur dioxide in the atmosphere and evaluate air quality.
  • Automotive, for applications related to vehicle exhaust gas detection or indoor air quality monitoring in vehicles.
