Rechargeable lithium battery with battery power display
Automatic power off when there is no operation in one minute
Forced Vital Capacity [FVC], Forced Expired Volume in one second [FEV], the ratio of FEV1 and FVC [FEV1%]. Peak expiratory flow (PEF), 25% flow of the FVC [FEF25], 75% flow of the FVC [FRF75] and average flow between 25% & 75% of the FVC [FRF2575] can be measured and display.
Besides, the testee condition can be shown by the ratio of the measured value and the predicted value.
Display: Flow rate -Volume chart, volume time chart
