  • Sulfur Dioxide Gas Sensors - SO2 Gas Detection | Pem-Tech, Inc.

    Sulfur Dioxide (SO2) Gas Sensors. Sulfur Dioxide (SO2), is a colorless gas with a strong odor. Sulfur dioxide is not combustible but it is considered an extremely toxic gas. When combined with water, sulfur dioxide becomes sulfuric acid which is highly corrosive and cause chemical burns. It is important to monitor sulfur dioxide levels for two main reasons: because industrial buildings such as power plants emit large amounts of sulfur dioxide and sulfur dioxide is a highly reactive gas.
