Portable device for testing pulmonary function, it adopts differential pressure acquisition principle to measure over 100 parameters related to Forced Vital Capacity (FVC), Ratio (FEV1/FVC)Vital Capacity (VC), Maximal Voluntary Ventilation (MVV) and Minute Ventilation (MV) functions.

Real-time displays respiratory waveform: flow-volume loop and volume-time curve, which is applicable for diagnosis and therapeutic evaluation of lung diseases.
