The proportional standard gas passes through the air inlet 21, the first sub-channel 2411, the second sub-channel 2412, the parallel channel 242 and multiple solenoid valve docking ports 22 in turn. The multiple solenoid valve docking ports 22 are connected to the corresponding CO solenoid valve 10, and the CO standard gas enters the gas analyzer for calibration. The gas concentration data detected by the gas analyzer is compared with the gas concentration data equipped with the dynamic calibrator in the quality control instrument to obtain the error of the gas analyzer. The detected gas flows to multiple gas exhaust ports 23 through the docking channel 25.
