Mini‑Wrigh Peak Flow Meter – ISO‑Accurate Mechanical PEF Meter, Standard & Low‑Range Models
The Mini‑Wright Peak Flow Meter, produced by Flexicare (Group) Ltd under the Clement Clarke brand, is the long‑standing mechanical gold standard for monitoring peak expiratory flow (PEF) in asthma and COPD management. Individually assembled and calibrated, it is one of only two mechanical meters shown in independent studies to meet ISO 23747 accuracy standards—making it the trusted choice in clinical and home settings
Models & Measurements
-
Standard Range: Measures PEF from 60 to 880 L/min—suitable for most adults and teenagers.
-
Low‑Range Model (Mini‑Wright AFS): Covers 30 to 400 L/min, ideal for young children, elderly users, or those with very low PEF values.
-
Integral one‑way valve prevents inadvertent inhalation during measurement—enhancing safety in multi-user environments
-
Individually calibrated units ensure repeatable accuracy; each meter is quality checked during assembly
Clement Clarke's flagship range of peak flow meters are first choice for healthcare professionals when it comes to the measurement of peak expiratory flow. The Mini-Wright brand is recognised worldwide as the 'Gold Standard' in asthma management. Each Mini-Wright device is individually hand calibrated, to ensure maximum accuracy.
Peak flow meters allow patients to monitor their asthma; Peak Expiratory Flow (PEF) is a measurement of how fast a patient can blow out. When a patient is well their PEF is higher, when the airways are narrow (as in asthma) PEF is lower.
