Zusammenfassung:The present invention relates to an apparatus and a method of measuring dust capable of measuring dust in a flow path. The apparatus to measure dust comprises: a flow path formation portion to form a flow path in which fluid including dust moves; a light irradiation portion to irradiate light in the flow path; a light detection portion to detect scattered light from the dust in the flow path to convert into an electrical detection signal, and including a plurality of detection portions having different light detection ranges; and a control portion to control the flow path formation portion, the light irradiation portion, and the light detection portion wherein the control portion receives detection signals from the detection portions, corrects an offset with respect to the received detection signals, and is able to measure a concentration of the dust based on the detection signal with the corrected offset. 유로 내의 먼지 농도를 측정할 수 있는 먼지 측정 장치 및 방법에 관한 것으로, 먼지 측정 장치는, 먼지가 포함된 유체가 이동하는 유로를 형성하는 유로 형성부와, 유로에 광을 조사하는 광 조사부와, 유로의 먼지로부터 산란된 광을 검출하여 전기적인 검출 신호로 변환하고, 서로 다른 광 검출 범위를 갖는 다수의 검출부를 포함하는 광 검출부와, 유로 형성부, 광 조사부 및 광 검출부를 제어하는 제어부를 포함하고, 제어부는, 다수의 검출부로부터 검출 신호들을 수신하고, 수신되는 검출 신호들에 대한 오프셋(offset)을 보정하며, 오프셋이 보정된 검출 신호를 토대로, 먼지 농도를 측정할 수 있다.
