The instrument is a gas analyzer independently developed by our company for environmental monitoring and industrial field exhaust online gas analysis. The analyzer is mainly intended to measure concentrations of gases such as SO2, NOx and O2, and has the characteristics of high measurement accuracy, high stability and reliability, and short response time. ♦ Features 1 n SO2 and NOx are measured using UV DOAS. Compared with traditional NDIR, the measurement accuracy is theoretically immune to light attenuation caused by background gases, and there is substantially no zero shift; 2s High-resolution...

SO2 and NO have obvious characteristic absorption spectral lines in the range of 200-320 nm, so it is very suitable to simultaneously measure these two gases by ultraviolet spectrometry. UV absorption cross section^^hlKKttM 3) DOAS DOAS is the English abbreviation for differential optical absorption spectroscopy. The basic principle is to distinguish and invert the concentrati on of the gas to be measured by using the narrow-band absorption characteristics of the molecules of the substance to be measured. The absorption of light by the sample gas can be divided into two parts: one part changes...
