ABSTRACT:
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.
