Description

hand-held equipment for checking lung conditions, adopts the mode of infrared interruption for measuring relative items, and be applicable for hospital, family for routine test.

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.*Taking on the functions of data memory, deleting, uploading and reviewing.*Wireless transmission (be applicable for SP10W)*Display trend curve.*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.
