CO2 and H2O are important combustion products of hydrocarbon fuels. This paper uses wavelength modulation spectroscopy (WMS) to simultaneously measure the pressure, temperature and CO2 component concentration information. Two absorption lines near 2.7um were selected, and the measurement experiment was carried out on the high-temperature furnace. The results showed that the measurement error of the three parameters was within 6% under the conditions of less than 1atm, 300-1200K temperature range and 10% concentration range, which verified the feasibility and accuracy of the method.
