4-SO2-20 4SO2-20 Electrochemical Gas Sensor Hydrogen Sulfide Sensor Classic Line for Gas Leak Detector
Core Features:
High Selectivity & Accuracy: Specifically responds to SO2 with minimal interference from common gases, ensuring precise concentration measurement.
Linear Output: The generated current is linearly proportional to SO2 concentration, simplifying signal processing and calibration.
Compact & Low Power: Standard 20.2mm diameter fits most portable detectors; low operating current supports battery-powered devices.
Stable Performance: Built-in electrolyte and electrode protection design reduces drift, maintaining reliability over long-term use.
Wide Environmental Adaptability: Operates stably in a broad temperature and humidity range, suitable for indoor and outdoor monitoring.
Typical Applications:
Industrial Emission Monitoring: Used in power plants, smelters, and chemical factories to monitor SO2 emissions from flue gas, ensuring compliance with environmental standards.
Environmental Air Quality Supervision: Integrated into ambient air quality monitoring stations or portable detectors for environmental protection departments to track atmospheric SO2 levels.
Indoor Safety Monitoring: Applied in laboratories, chemical storage rooms, and industrial workshops where SO2 may leak, alerting workers to potential health hazards.
Marine & Shipping Industry: Deployed in ship exhaust gas monitoring systems to detect SO2 emissions from marine engines, meeting international maritime pollution regulations.
Agricultural & Food Processing: Used in fruit storage or food processing facilities to monitor SO2 (used as a preservative) concentration, preventing excessive residues.
