Sulfur dioxide analyzer DOAS-2000

nitrogen dioxideammoniaozone

DOAS-2000 online differential ultraviolet spectrometer is mainly used in the gas analysis industry. The main detection occasions: flue gas emission, desulfurization and denitrification, boiler exhaust, VOCs exhaust, sewage pipeline gas detection and analysis, etc. System composition: sampling unit, sample gas pretreatment unit, gas analysis unit. On-line hydrogen sulfide DOAS-2000 features: ★ Explosion-proof and waterproof design, protection grade IP66, outdoor type, fast detection, reliable and stable; ★ Built-in high-efficiency two-stage condensation dehumidification and dust removal pretreatment system, automatic control integrated design, effectively reduce SO2 loss, prevent water vapor interference, and is more suitable for working conditions with high humidity and low flue gas component concentration; ★ Using differential absorption spectroscopy technology (DOAS), the temperature drift is small, the measurement accuracy is high, and the ultra-low concentration can be measured; ★ Long-life pulsed xenon lamp cold light source, short warm-up time and long service life; ★ Built-in long optical path gas cell, dual range design for NOx and SO2 analysis, automatically switch range control according to the concentration value; ★ The concentration curve of each flue gas component is displayed in real time, and the curve display ratio can be adjusted; ★ Low detection limit, not affected by moisture and dust, strong anti-interference ability, can avoid cross-interference between gases; ★ Built-in heating device, automatically start the heating function at low temperature, so that the analyzer can be used in severe cold areas;
