Abstract
The present invention relates to a dust measuring apparatus and, more particularly, to a miniaturized fine dust measuring apparatus. According to one embodiment of the present invention, a non-sampling fluid is discharged irrespective of a speed change of an external fluid, thereby providing a particle sampling probe and a miniaturized fine dust measurement apparatus that provide uniform-speed sampling. Accordingly, it is possible to eliminate a restriction on a place for fine dust measurement.
