  • Sulfur Dioxide Gas Detectors | SO2 Detectors | Industrial

    Sulfur Dioxide Gas Detectors (SO2 Detectors) Sulfur dioxide (SO2) is a colorless, extremely toxic gas with a strong odor. Common applications of sulfur dioxide include sulfuric acid production, pulp and paper mills, chemical processing, food and beverage, coking operations and petroleum refineries. Since coal and petroleum often contain sulfur compounds, their combustion will generate SO2 unless the sulfur compounds are removed before the fuel is burned.
