Zusammenfassung:	The present invention relates to a system for precisely measuring fine dust precursors, and relates to, among devices for measuring the concentrations of fine dust precursors NOx and SOx using the tunable diode laser absorption spectroscopy (TDLAS) method, a device capable of controlling the temperature of a measurement cell without vibration by using a thermoelectric element. La présente invention concerne un système de mesure précise des précurseurs de poussière fine, et concerne, parmi les dispositifs de mesure des concentrations des précurseurs de poussière fine de type NOx et SOx à l'aide d'une technique de spectroscopie d'absorption laser à diode ajustable (TDLAS), un dispositif apte à réguler la température d'une cellule de mesure sans vibrations à l'aide d'un élément thermoélectrique. 본원 발명은 미세먼지 전구물질의 정밀 측정 시스템에 관한 것으로서, 미세먼지의 전구물질인 NOx, SOx의 농도를 TDLAS(Tunable Diode Laser Absorption Spectroscopy)기법을 사용하여 측정하는 장치 중 측정 셀의 온도를 열전소자를 사용하여 진동없이 제어할 수 있는 장치에 관한 것이다.
