ASSEMBLY FOR MEASURING FINE DUST AND APPARATUS FOR MEASURING FIND DUST HAVING THE SAME, AND SYSTEM FOR MEASURING FINE DUST HAVING THE APPARATUS FOR MEASURING

摘要

The present invention relates to a fine dust measuring assembly for measuring fine dust concentration, a fine dust measuring device having the same, and a fine dust measuring system having the fine dust measuring device. The fine dust measurement assembly according to the present invention includes a casing having an air inlet through which atmospheric air is introduced, disposed on the other side of the casing, and irradiating light to measure the concentration of fine dust in the air introduced into the air inlet to measure the amount of scattered light a plurality of bulkhead units and a plurality of bulkhead units disposed between the air inlet and the measuring unit along the inflow direction of the air flowing into the air inlet to form a zigzag flow path for the air flowing from the air inlet to the measuring unit. It characterized in that it comprises a washing unit which is disposed corresponding to the upper portion and is reciprocally moved in the transverse direction in the inflow direction of air between the plurality of bulkhead units forming a zigzag flow path to selectively contact both sides of the bulkhead unit.
