Contec SP10 Spirometer

Contec SP10 Spirometer is a hand-held device for checking lung conditions, adopts the infrared mode for measuring relative items, and is applicable for hospitals and clinics for routine testing.
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 test 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.Performance:
