This device could calculate the amended gas volume and its amended flow, and provide the standard values such as vital capacity, forced vital capacity, peak expiratory flow, maximum voluntary ventilation, etc. for spirometry analyzers. Its principal indicators have reached the requirements of the spirometry standard recommended by the European Respiratory Society and the American Thoracic Society. In this paper, the social significance of this calibration device was briefly introduced, its basic working principle was interpreted, and its main physical parameters and basic functions were listed too.   Key words: Spirometer; Calibration; Spirometry calibration device; Simulation; Quality control; Value traceability   Editor：liyan
