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 Our B-Arm Digital Peak Flow Meter with Bluetooth connectivity and built-in memory is a portable respiratory monitoring device designed to help individuals monitor and manage their respiratory conditions and track airway performance effectively. This Bluetooth-enabled flow meter records Peak Expiratory Flow (PEF) and Forced Expiratory Volume (FEV1) values, delivering precise expiratory airflow measurement for routine respiratory assessment and pulmonary function monitoring. It also features built-in memory with the capacity to store up to 300 readings, enabling users to review historical data and track respiratory performance over time. With a measurement range of 60L/min ~ 840 L/min, this digital spirometer provides real-time lung function test results immediately. It is designed to automatically display values on a clear LCD screen. Its compact, lightweight design allows easy portability, making it suitable for daily use and routine health checks. Equipped with built-in Bluetooth connectivity, this respiratory device syncs with a mobile application for structured respiratory tracking and long-term lung function assessment. The package includes 2 mouthpieces to support hygienic and comfortable use across different age groups. Users can analyse recorded spirometer data to observe respiratory trends over time, supporting regular peak flow tracking. By tracking peak respiratory flow regularly, users can gather measurable data that may assist in understanding changes in lung condition and supporting structured asthma action plans under medical guidance. Designed for structured respiratory care, this device supports lung health monitoring routines and pulmonary rehabilitation programs. Its rechargeable design eliminates disposable batteries while maintaining reliable electronic peak flow measurement. The ergonomic handheld design ensures a comfortable grip and simple one-touch operation for convenient daily testing. This compact and well-designed lung monitoring device is suitable for personal use, caregiver-assisted monitoring, and clinical settings, providing organised digital airflow measurement through simple and convenient handheld operation. Suitable for athletes, asthma patients, COPD individuals, exercise-focused users, and oxygen users for routine lung function monitoring. HOW TO USE: POWER ON: Press the home button to turn ON the digital peak flow meter; “Go†appears on the screen, indicating readiness for lung function testing. PLACE MOUTHPIECE: Take a deep breath and seal your lips fully around the mouthpiece to ensure accurate airflow measurement. HOLD CORRECTLY: Do not block the mouthpiece with your tongue or cover the rear air outlet with your hand to maintain proper expiratory flow meter performance and reliable peak flow readings. BLOW & MEASURE: Blow out as fast as possible; after two beeps, the result automatically displays, completing the peak expiratory flow rate test and respiratory assessment. REPEAT TEST: Press the home button to repeat twice and record the highest value as the final result for accurate peak flow monitoring tracking. POWER OFF: Press and hold the home button for about 3 seconds to switch OFF the portable respiratory monitoring device. DOWNLOAD APP: Install the Sonmol PEF app via Google Play or by scanning the QR code to enable Bluetooth flow meter connectivity and digital spirometer data tracking. ALLOW PERMISSIONS: Enable required permissions for the nearby device connection to support respiratory monitoring and airflow monitoring device functions. PAIR DEVICE: Keep the device ON and open the app to find the device name for connection and begin respiratory data tracking and lung health monitoring. SYNC DATA: Select the device to connect and sync readings for storage in the app, supporting ongoing peak flow tracking, pulmonary function monitoring, and respiratory health assessment. NOTE: Setting the correct expected value ensures accurate peak flow zone indication (Green, Yellow, Red) and proper Bluetooth data tracking in the app. PRO-TIP: For structured respiratory care, a mesh nebulizer can be used to support prescribed medication delivery in fine mist form, helping maintain airway comfort as part of daily breathing management. A respiratory muscle trainer may be incorporated into routine breathing exercises to support controlled inhalation and exhalation practice. When used alongside a Bluetooth Peak Flow Meter, users can monitor Peak Expiratory Flow (PEF), lung function, and track measurable airflow measurement changes while maintaining structured breathing capacity tracking routines under medical guidance. When this device is used alongside an inhaler spacer, users can monitor airflow changes before and after inhalation therapy, helping assess response to medication while maintaining accurate respiratory monitoring records through the connected mobile application. A humidifier may support ambient air moisture for comfort in dry environments, while the digital peak flow monitor provides measurable airflow data, functioning as a portable spirometer and respiratory function monitor for structured daily tracking. A 3-ball spirometer is commonly used for breathing exercises and visual lung expansion training, whereas the Bluetooth-enabled peak flow meter delivers quantifiable expiratory flow meter readings and historical respiratory data tracking, supporting consistent lung testing, asthma monitoring, and COPD monitoring. Unlike a pulse oximeter, which measures oxygen saturation levels in the blood, the peak flow meter focuses on airway function by measuring Peak Expiratory Flow (PEF) and airflow performance to support structured respiratory monitoring.
