Williams, R., A. Kaufman, AND S. Garvey. DYLOS DC110. U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-15/116 (NTIS PB2015-104895), 2015.
The National Exposure Research Laboratory’s (NERL’s) Human Exposure and Atmospheric Sciences Division (HEASD) conducts research in support of EPA’s mission to protect human health and the environment. HEASD’s research program supports Goal 1 (Clean Air) and Goal 4 (Healthy People) of EPA’s strategic plan. More specifically, our division conducts research to characterize the movement of pollutants from the source to contact with humans. Our multidisciplinary research program produces Methods, Measurements, and Models to identify relationships between and characterize processes that link source emissions, environmental concentrations, human exposures, and target-tissue dose. The impact of these tools is improved regulatory programs and policies for EPA.
The Dylos DC1100 air quality monitor measures particulate matter (PM) to provide a continuous assessment of indoor air quality. The unit counts particles in two size ranges: large and small. According to the manufacturer, large particles have diameters between 2.5 and 10 micrometers (µm), where a micrometer is 1/1000th of a meter. Small particles have diameters from 0.5 µm up to 2.5 µm. The DC1100 stores up to 30 days of air quality history. This operating procedure explains what you need to do to collect quality PM data using the Dylos DC1100 for your monitoring project.
