Electronic spirometer SP10

hand-held

SPIROMETER is a hand-held equipment for checking lung conditions, adopts the infrared mode for measuring relative items, and is applicable for hospital, clinique for routine test. Main Features ■Forced Vital Capacity (FVC), Forced Expired Volume in one second (FEV1), the ratio of FEV1 and FVC (FEV1%), 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. Besides, the testee condition can be shown by the ratio of the measured value and the predicted value. ■Flow rate-volume chart, volume-time chart display. ■Data memory,delete, upload and review. ■Trend chart display. ■Scaling(Calibration). ■Information prompts when volume or flow goes beyond the limits. ■Automatic power off when there is no operation in one minute. ■Rechargeable lithium battery and with charging tips. ■Battery power display.
