Introduction
→ SPIROMETER is a hand-held equipment for checking lung conditions, adopts the infrared mode for measuring relative items, and is applicable for hospital, clinique,family 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.
→ Wireless transmission.
→ 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.
