Paediatric-Scaled Three-Zone System for Asthma Action Plans
The PF120C uses an adjustable colour-coded three-zone indicator ? green (good), yellow (caution), red (danger) ? calibrated to each child’s personal best reading. The 50?400 L/min measurement range is specifically scaled for paediatric lung volumes, unlike adult meters which begin at 60 L/min and may underread or fail to register in younger or smaller patients. Easy-to-read graduated numbers on the scale allow children, caregivers, and school nurses to interpret readings quickly, supporting consistent use of written asthma action plans without clinical interpretation at every reading.
EN ISO 23747:2009 Compliant with Accuracy Assurance
Like the adult PF120A, the PF120C is manufactured to EN ISO 23747:2009 ? the international standard governing peak expiratory flow meter performance ? and carries CE approval. This compliance confirms measurement accuracy and repeatability across the full paediatric range, providing clinicians with reliable serial measurements for monitoring asthma severity, assessing bronchodilator response, and identifying early deterioration in paediatric patients.
Washable, Portable, and Battery-Free
The PF120C requires no batteries or electronics ? a mechanical design that eliminates device failure due to power in any care setting, including home, school clinic, emergency department, and general practice. The washable body supports hygienic reuse between sessions, and the unit is compatible with disposable mouthpieces for multi-patient environments. Its compact, lightweight form is easily carried in a bag by child patients or caregivers for daily home monitoring. Storage is rated for 10?C?35?C at 30?75% RH.
