Nozzle holes (15a) each provided with a tapered portion (15t) on the upstream side of a straight tube portion (15s) are disposed on a nozzle sheet (15) in a lattice form, air-borne bacteria passed through the nozzle sheet (15) are efficiently trapped by a culture medium to produce colonies, and visually count the number of colonies to thereby measure a clean level.

Des orifices d'ajutages (15a) chacun doté d'une partie conique (15t) du côté amont d'une partie tubulaire droite (15s) sont disposés sur une plaque d'ajutages (15) en une forme de grille, les bactéries en suspension dans l'air ayant passé à travers la plaque d'ajutages (15) sont piégées efficacement par un milieu de culture pour produire des colonies, et compter visuellement le nombre de colonies afin de mesurer ainsi un niveau de propreté.
