l SO2 and NO are measured by ultraviolet difference spectroscopy. Compared with traditional NDIR, the measurement accuracy is not affected by moisture and dust in theory, and there is basically no zero drift
l High resolution spectrometer is used for spectral analysis, and the spectrometer is specially optimized for flue gas analysis
l The instrument has high internal control accuracy and good environmental adaptability
l The deuterium lamp with high stability is used as the light source, and the instrument has good stability
l No optical moving parts, no optical moving parts such as cutting wheel, filter wheel and interferometer, high reliability
l Modular design, light source, spectrometer, core circuit, gas chamber, oxygen sensor, etc. adopt modular design, with high reliability, good scalability and easy maintenance
l Acid adding anti adsorption is adopted to reduce the loss rate of condensed components, and the loss rate of SO2 is controlled within 5%
l Heating of sampling probe rod, applicable to monitoring of low temperature environment and wet flue gas
