Main Performance
Measure Forced Vital Capacity (FVC).
Measure Forced Expired Volume in one second (FEV1), the ratio of FEV1 and FVC (FEV1%), and the testee condition can be shown by the ratio.
Peak expiratory flow (PEF), 25% flow of the FVC (FEF25), 75% flow of the FVC (FEF75) and average flow between 25% and 75% of the FVC (FEF2575) can be measured.
Flow rate-volume chart, volume-time chart display.
Battery power display.
Automatic power off when there is no operation in one minute.
Data memory function.
Data memory, delete, upload and review.
Rechargeable lithium battery.
