Document Type and Number:
WIPO Patent Application WO/2016/093447
Kind Code:
A1
Abstract:
The present invention relates to a microbalance-based fine dust measuring device which continuously measures fine dust concentration by automatically replacing filter papers, or performs automatic calibration using a balance weight for calibration, wherein a plurality of concentration measurement filter paper holders (60), on which filter papers are seated, and a balance weight filter paper holder (60a) are seated on a holder mount plate (50), and wherein the holder mount plate (50) is rotated, thereby replacing the filter paper holders (60, 60a) and being mounted on the free end (11) of a vibration tube (10), the balance weight filter paper holder (60a) being for obtaining a mass conversion coefficient, which is the correlation coefficient between the mass of fine dust and the vibration frequency.
