In view of the problems existing in the sampling flow calibration of the air sampler,the calibration re-sults of the sampler under different operating conditions are studied by using different calibration equipment.The re-sults show that the calibration equipment should be connected to the inlet of the sampler during calibration,and when the portable flow calibrator based on the principle of pressure difference is used as the calibration equipment,the flow point selection and the installation of the sampling parts of the relevant equipment should be consistent with the actual use conditions.
