Sulfur dioxide gas alarm

The sulfur dioxide gas alarm detects the concentration of sulfur dioxide in the air through an electrochemical sensor. The sensor reacts with the gas to generate an electrical current signal, where a higher concentration results in a larger current. It is used to monitor sulfur dioxide leaks in industrial processes such as printing and papermaking, ensuring the safety of the work area.
Selection
When selecting, ensure the detection range covers process requirements, consider sensor lifespan and calibration cycles, evaluate the impact of environmental temperature and humidity on the instrument, verify that the explosion-proof rating matches on-site conditions, and confirm that the alarm recording function meets management requirements.
