Abstract With the deepening of national ultra-low emission policy, higher requirements are put forward for accurate measurement of pollutant concentration in the flue gas. Based on Fourier transform infrared(FTIR) spectrometer, an accurate measurement system for nitric oxide (NO) gas under high temperature and water content was established. The absorption spectra of 5%～20% water vapor and 5～40μmol/mol NO were measured before and after mixing at 191℃. The NO concentration was accurately determined by correcting the absorbance of H2O in the mixture, and system measurement uncertainty was evaluated. The results show that the relative deviation between the measurement result of NO in high temperature water-containing and the standard gas value is less than 1.8%, and the relative expanded uncertainty of the measurement is 2.78% (k=2). The system has good measurement accuracy and stability. It is of great significance to the implementation of the national ultra-low emission policy and the collection of environmental taxes.
