Peak Flow Meter Portable Spirometer Measure PEF & FEV1 Lung Tester with Red Yellow Green Risk Indicator for Asthma COPD for Adult Kids
Ultra-Accurate Differential Pressure Sensor: The Sonmol electronic spirometer, equipped with a differential-pressure-type sensor, accurately measures two key parameters: PEF (Peak Expiratory Flow) and FEV1 (Forced Expiratory Volume in one second). This provides an ultra-accurate reflection of your pulmonary ventilation function and the degree of airway obstruction, all without the need for sensor calibration
Compliance with Health Guidelines: Our spirometer meets the guidelines set by the U.S. Department of Health and Human Services. Additionally, it includes a free PEF expected value calculation tool, which can be accessed by simply scanning the provided QR code
Risk Indicator & Customizable Expected Values: The Sonmol peak flow meter is equipped with an LCD screen that automatically displays test values for easy recording. You have the flexibility to set your personal expected value, and each test will indicate your control condition with the risk indicator. Please note that the device will not display red, yellow, or green Risk Indicators without the expected value properly set
Pocket-Sized Spirometer with Long Lifespan: Our spirometer is powered by two AAA batteries (included), ensuring up to a year of daily use. Its compact, pocket-sized design allows for easy portability in your bag, enabling you to check whenever and wherever you need
Clean and User-Friendly: Featuring an open pipe design, our spirometer simplifies mouthpiece cleaning and disinfection. Just wipe it and you won't need to worry about residual contaminants
