Evidence-based evaluation by medical professionals
"The Rossmax PF120 Series offers a highly reliable and cost-effective mechanical solution for daily asthma and COPD management across all age groups."
The Rossmax PF120 Series, comprising the PF120 A (Adult) and PF120 C (Child) models, represents a standard of precision in mechanical respiratory monitoring. These Class II medical devices are engineered to measure Peak Expiratory Flow Rate (PEFR) using a time-tested spring-and-piston mechanism. The PF120 A features a measurement range of 60-800 L/min BTPS, while the PF120 C is tailored for pediatric users with a 50-400 L/min BTPS range. A key technical advantage is the built-in flexible three-zone management system, which uses adjustable color-coded indicators (Green, Yellow, Red) to help patients track their respiratory status against their personal best. The devices comply with the EN ISO 23747:2009 standard, ensuring accuracy within ± 10 L/min or ± 10% of the reading. Constructed from washable medical-grade ABS plastic, the series is designed for long-term durability and hygiene. While purely mechanical and lacking digital data logging, the PF120 Series remains a benchmark for affordable, reliable home monitoring in 2026.
