Flue gas analyzer Gasboard-3600UV

monitoringonlineUV-DOAS

Introduction The high-temperature UV flue gas analyzer adopted ultraviolet differential (UV-DOAS) technology and combined with Hot & Wet sampling technology to achieve direct measurement of high-temperature raw flue gas. It can simultaneously measure the concentration of SO2, NO, NO2 (other gases can be extended on request) in the emission gas from stationary sources of air pollution. Compared with the traditional Cold & Dry method analyzers, it requires no condensing equipment and can effectively avoid the condensation loss of SO2 and other sour gas substances, and reach the higher measurement accuracy. Features • Raw flue gas is directly analyzed inside the analyzer through heated sampling line, without any condensing loss of SO2 and other components. • Long optical path with multiple refletion design, suitable for ultra-low level emission monitoring. • Direct measurement of NO and NO2, no NOx converter required. • Optical path without any mechanical moving parts, strong vibration resistance. • Measuring chamber can be cleaned, convenient for maintenance. • Pulsed xenon lamp source, good stability, more than 5 years of service life. Specifications Sampling Method: Hot & Wet Gas & Range: NO: 0~100 to 1000mg/m3; NO2: 0~100 to 1000mg/m3; SO2: 0~100 to 1000mg/m3（Other range can be customized） Principle: UV-DOAS Resolution: 0.01mg/m3 Linear Error: ≤±1%F.S.
