2050 type comprehensive ambient air sampler Introduction: This instrument utilizes the filter weighing method to capture total suspended particulate matter (TSP) and inhalable particulate matter (PM10) or fine particulate matter (PM2.5, optional) in ambient air; it employs the solution absorption method to collect various pollutant gas components (such as SO2, NOx, etc.) in ambient air and indoor air; it can also be used for sampling volatile organic compounds (VOCs) in ambient air. It can be used by departments such as environmental protection, health, labor, safety supervision, military, scientific research, and education for routine or emergency monitoring of particulate matter, gaseous substances, and aerosols.
