Abstract：Gas dilution device is more and more widely used in various types of gas detection alarm and gas analyzer. In this paper，the same carbon monoxide infrared gas analyzer is calibrated at the selected calibration point through standard gas and gas dilution device. Combined with the calibration data such as indication error and indication repeatability，the differences between the two calibration methods are analyzed，which provides a reference for metrological colleagues in practical work in the future.
