PARTICLE COUNTING DEVICE WITH WIDE RANGE SIZE

摘要

PURPOSE: A particle measuring unit is provided to individually measure with a disassemblable structure. CONSTITUTION: A particle measuring unit(10) comprises a coarse particle detection unit(200), micro particle detection unit(300), driving unit(500), and controller. The coarse particle detection unit counts particles which are larger than a pre-set size from an aerosol. The micro particle detection unit is placed at a location downstream of the coarse particle detection unit. The micro particle detection unit has a condensed particle counter(400). The controller electrically communicates with the coarse particle detection unit, micro particle detection unit, and driving unit.
