Measurement PrincipleUV-DOAS
Overview
KSA-1000UV is an emission gas analyzer using UV differential optical absorption spectroscopy (UV-DOAS), continuously measuring three gas components—NO, NO2 and SO2—at the same time.
It measures NO and NO2 directly without a NOx converter, minimizes the effect of gas flow fluctuations and has built-in sensor self-diagnosis.
It is used for industrial stack emission monitoring, waste-to-energy facilities, SOx and NOx measurement at industrial facilities, and gas analysis at pollution control facilities.
