SPECTRO’s model SLE-FPS105 is an advanced fine dust sampler, which can be used to determine the concentration of particulate matter of size less than 2.5μ in atmosphere. It has been specifically designed to comply with EPA reference method for determination of PM2.5, when used without Impactor (2.5μ cut stage), the system may be optionally used for particulate matter less than 10μ.

Ambient air enters the SLE-FPS105 system at a constant sampling rate at 1 m³/hr by a suitable critical orifice through an omni-directional inlet designed to provide a clean aerodynamic cut-point for particles greater than 10 microns. Particles in the air stream finer than 10 microns proceed to a second impactor that has an aerodynamic cut point at 2.5 microns. The air sample and fine particulates exiting from the PM2.5 impactor is passed through a 47mm diameter Teflon filter membrane that retains the FPM. Instrument has inbuilt oil free brushless blower and dry gas meter to have direct volume of air passed through the system.
