This instrument uses the filter membrane gravimetric method to collect total suspended particulates (TSP), inhalable particulates (PM10), or fine particulates (PM2.5 optional) in ambient air; it uses the solution absorption method to collect various gaseous pollutants (SO2, NOx, etc.) in ambient air and indoor air; it can also be applied to solid-phase adsorption sampling of VOCs in ambient air. It is suitable for routine or emergency monitoring of particulate matter, gaseous substances, and aerosols by environmental protection, health, labor, safety supervision, military, scientific research, education, and other departments.
