A sample probe is provided for sampling aerosols within a wall cavity. The
sample probe includes a hollow tubular body having a distal end, an
intermediate portion, a proximal end and a central passageway. The distal
end includes a sharp beveled point provided to inhibit the blockage of a
distal open inlet if the distal end is positioned against an object. The
probe further includes one or more holes projecting through the probe's
tubular body, preferably positioned substantially adjacent to the probe's
distal end. The probe further includes a radially projecting region
adapted for sealing a hole or opening formed to obtain access to a wall
cavity. Moreover, the probe includes a proximal open outlet adapted to
connect to the inlet of an aerosol sampling cassette.
