Spirometer

Product Details:

Product Description:

• Rechargeable lithium battery with battery power display
• Automatic power off when there is no operation in one minute
• Forced Vital Capacity [FVC], Forced Expired Volume in one second [FEV], the ratio of FEV1 and FVC [FEV1%]. Peak expiratory flow (PEF), 25% flow of the FVC [FEF25], 75% flow of the FVC [FRF75] and average flow between 25% & 75% of the FVC [FRF2575] can be measured and display.
• Besides, the testee condition can be shown by the ratio of the measured value and the predicted value.
• Display: Flow rate -Volume chart, volume —time chart
• Data memory, delete, upload and review
• Trend chart display
• Scaling [Calibration]
• Information prompts when volume or flow goes beyond the limits
• Ratio of FEV1 and FVC can be measured
• Software interface and trend chart display
• Battery backup: 4 hours

Technical Features:

• Max Volume: 10L
• Flow Range : 1L/s~16L/s
• Volume accuracy: ±3% or 0.05L [Whichever is greater]
• Flow accuracy: ±10% or 0.3L/s [Whichever is greater]
• The highest resistance to flow within the measurement is 6Pa/L/s, and this resistance may occur at 14L/s

• Wireless Interface Through Bluetooth
