● SO2 and NO use UV differential spectroscopy. Compared with traditional NDIR,the measurement accuracy is not affected by moisture and dust, and there is basicallyno zero drift.
● Using a high-resolution spectrometer for spectral analysis, the instrument has a verylow detection limit.
● The internal temperature control precision of the instrument is high, and theenvironmental adaptability is good.
● The light source adopts high stability deuterium lamp, and the instrument has goodstability.
● No optical moving parts, no cutting wheel, filter wheel, interferometer and otheroptical moving parts, highly reliable.
● Modular design, light source, spectrometer, core circuit, gas chamber, oxygensensor, etc. adopt modular design, with high reliability, good scalability and easymaintenance.
