  • 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.

    Dec 01, 2018 · Abstract. Development of high-performance nitrogen dioxide sensors is extremely important not only for industrial applications but also for environmental monitoring and health protection. For practical applications, gas sensors with high sensitivity for low concentrations of nitrogen dioxide are desired. Here, a simple process to fabricate high-performance gas sensors based on porous reduced graphene oxide (PRGO) through a simple drop-casting technique is presented.

    (OSHA) is 1.0 ppm. However, chlorine dioxide has a toxic threshold that is 10% of chlorine’s. So a monitor with just 0.1 ppm resolution would go into alarm as soon as it came across chlorine dioxide. This can lead to too many false alarms. Therefore, a chlorine dioxide monitor needs to have 0.01 ppm resolution. The RAE Systems ToxiRAE II (ClO
