Sonmol Digital Peak Flow Meter Portable (SMPF-2S)
Sonmol
by Vitalograph • Model: 4000 / 40000
The Vitalograph asma-1 is a handheld electronic respiratory monitor designed for home use to monitor asthma conditions. It utilizes a stator-rotor mass flow sensor to measure Peak Expiratory Flow (PEF) and Forced Expiratory Volume in one second (FEV1), providing more reliable data for clinicians than standard mechanical meters. The device automatically calculates and trends the user's results, featuring a large, easy-to-read display and a quality-of-blow indicator to ensure accurate test sessions.
Eligibility may vary by provider and plan. Check with your HSA/FSA administrator for specific details.
Evidence-based evaluation by medical professionals
"The Vitalograph asma-1 is an elite clinical-grade monitor that provides superior accuracy and the industry's most robust data logging for long-term respiratory tracking."
The Vitalograph asma-1 is a sophisticated electronic monitor designed for objective lung function testing in both home and clinical settings. As a Class II medical device, it measures both Peak Expiratory Flow (PEF) and Forced Expiratory Volume in one second (FEV1), allowing for a more nuanced clinical assessment of airway obstruction than basic peak flow meters. A primary engineering advantage of the asma-1 is its massive internal memory, which stores up to 600 sets of readings-far exceeding the standard 240 readings found in many competing digital monitors. The device features integrated quality prompts to ensure valid maneuvers and a customizable 'traffic light' system for immediate zone assessment relative to the user's personal best. The sensor technology is designed to meet or exceed rigorous international standards for spirometry, including ATS and ERS guidelines. While primarily a standalone electronic tool, its high-capacity logging and ability to generate detailed clinical reports make it a cornerstone of 2026 respiratory management for chronic patients.
