  • Why Measure for Sulfur Dioxide (SO2) in Homes Offices | E

    Sulfur Dioxide (SO 2) is a highly reactive gas that is part of a larger group of sulfur oxides or SOx gases. According to the U.S. Environmental Protection Agency, the largest sources of SO 2 emissions are due to “fossil fuel combustion at power plants (73%) and other industrial facilities (20%)”. Although residents in homes and offices at or near the “fenceline” of power plants and industrial facilities are most at risk of SO 2 exposure, the toxic gas can be leaked within any building.

  • CO2 Gas Concentration Defined | CO2Meter.com

    When measuring gases like carbon dioxide, oxygen, or methane, the term concentration is used to describe the amount of gas by volume in the air. The 2 most common units of measurement are parts-per-million, and percent concentration. Parts-per-million (abbreviated ppm) is the ratio of one gas to another. For example, 1,000ppm of CO2 means that if you could count a million gas molecules, 1,000 of them would be of carbon dioxide and 999,000 molecules would be some other gases.
