The FPF-S1 peak flow meter helps families track peak expiratory flow (PEF) at home with a simple one-blow routine. A turbine airflow structure with infrared interruption sensing measures PEF from 50-900 L/min, while the device stores up to 500 records and keeps the highest value from each measurement session. Lightweight at about 108 g without batteries, it runs on two AAA batteries and supports daily morning/evening breathing trend checks for users age 5+ with adult supervision when needed.
