B-Arm Sonmol Digital Peak Flow Meter with Bluetooth | Built-In Memory Stores 300 Readings | Pulmonary Function Meter with PEF & FEV1 for Lung Health Monitor | Asthma COPD Spirometer for Kids & Adults

Features

• BLUETOOTH PEAK FLOW METER: Our B-Arm Digital Peak Flow Meter with Bluetooth connectivity and built-in memory is designed for individuals undergoing pulmonary rehabilitation, tracking lung health, managing asthma or COPD, and supporting structured peak flow monitoring.
• DIGITAL PEF & FEV1 MEASUREMENT: This electronic peak flow meter functions as an expiratory flow meter, supporting lung capacity test, asthma monitoring, COPD monitoring, and routine lung health assessment with measurable airflow data.
• BLUETOOTH TRACKING & MEMORY STORAGE: Sync with a mobile app to monitor respiratory performance, track progress with treatments and lung exerciser, or sync data from the device to your phone. The device features built-in memory capable of storing up to 300 readings for reviewing and tracking respiratory performance over time.
• SUITABLE FOR MULTIPLE RESPIRATORY NEEDS: Ideal for athletes monitoring breathing performance, asthma patients managing peak flow levels, COPD individuals tracking lung function, exercise-focused users strengthening respiratory capacity, and oxygen users observing airway performance under medical guidance.
• PORTABLE & RECHARGEABLE DESIGN: Compact and lightweight, this portable spirometer meter is suitable for home lung testing, travel, and workplace respiratory checks without disposable batteries.
• ACCURACY & MEASUREMENT PERFORMANCE: The device provides reliable respiratory measurement with volume accuracy of 2.5% and flow rate accuracy of 10%. It supports a measuring range of Volume: 0.5L ~ 8L and Flow Rate: 60L/min ~ 840 L/min, enabling effective lung capacity testing and peak expiratory flow monitoring.
• COLOR RISK INDICATOR DISPLAY: The device features a clear PEF and FEV1 risk indicator system that helps users interpret respiratory results easily. Based on the displayed values, readings are categorized into Green (Normal 80%), Yellow (Moderate 5080%), and Red (Severe <50%) zones for Peak Expiratory Flow (PEF), while FEV1 values help identify Normal (80%), Mild (<80%), Moderate (<50%), and Severe (<30%) obstructive levels, supporting quick respiratory assessment and structured asthma monitoring.
