Online UV DOAS Flue Gas Analyzer

Gasboard-3000UV

Gasboard 3000UV is designed based on ultraviolet differential optical absorption spectroscopy (UV-DOAS) technology. Compared with the Luft NDIR and Micro-flow NDIR flue gas analyzer, it can measure ultra-low range (0-50mg/m3) of SO2 and NO, which is widely used in industrial emission monitoring to ensure the compliance with local emission regulation.
