Ambient Fine Dust Sampler - Model Fds 2.5 A | Advanced Pm2.5 Measurement System, High Precision Ptfe Filter Technology, 16.7 Lpm Flow Rate, 24-hour Sampling Capacity

Our company is well recognized manufacturer, exporter and supplier of premium quality assortment of PM2.5 Sampler in Navi Mumbai, Maharashtra, India. NETEL is pleased to provide you with an advanced Ambient Fine Dust Sampler, Model FDS 2.5Au A measurement of mass concentration of fine particulate matter having an aerodynamic diameter less than or equal to a nominal 2.5 micrometer (PM 2.5). The instrument has been specifically designed to meet or exceed the operational requirements EPA designated reference method for the determination of fine particulate matter as PM 2.5 in the atmosphere as described in 40 CFR Chapter I a Part 50, Appendix L. In principle, an electrically powered sampling pump draws ambient air at a constant volumetric flow rate of 16.7 LPM through a specially designed a Sampling Inleta which separates particles larger than 10 (50 % cut point) and allows smaller particles to enter an internal particle size separator ( WINS Impactor) where the suspended particulate matter in the PM 2.5 size range is collected on a PTFE Filter over the specified sampling period of 24 hours. Each filter is weighed (after moisture & temperature conditioning) before & after sample collection to determine the net increase in weight due to collection of PM 2.5 particulate matter.
