Abstract

The present invention relates to a system capable of measuring particulates which is technically characterized by including: a nozzle formed in the shape of a tube; a light measurement unit which is constituted by a light source supplied as energy and a photodetector and is provided adjacent to the nozzle; a probe which has a hollow shape and into which one end of the nozzle is inserted; a particle measurement unit provided adjacent to the light measurement unit to measure the particulates introduced through the nozzle; an evaluation model unit linked to the particle measurement unit to evaluate the volume of the particulates on the basis of software; an evaluation process unit linked to the evaluation model unit to evaluate each of a volume size distribution of the particulates, an integration with respect to the size of each of the particulates and a time, and the volume concentration of the particulates; a purge supply unit linked with an outer end of the probe to supply a purge into the probe; and a velocity control unit provided adjacent to the probe to control the velocity of the purge supplied to the probe, thereby enabling the improvement of the reliability of particulate monitoring because it is possible to continuously monitor characteristics of the particulates such as concentration, size distribution, particle grade, and the like of the particulates extracted from an atmospheric gas or an exhaust gas.
