The Rossmax PF120A is a high-quality peak flow meter, complete with easy to read colour coded indicators. It is designed to measure peak expiratory flow rate (PEFR), which indicates how well air moves out your lungs. If your PEFR is low this may be a sign of asthma or narrowed airways. This is a useful device for asthmatics so they can keep an eye on their PEFR to see if there's any significant changes.
Designed for adults, this peak flow meter has an advanced built-in 3-zone management system that ensures accuracy with a measurement range of 60-800 L/min. Not only is this device accurate, it is also very user friendly with easily readable numbers, it is washable and can be used with a disposable mouthpiece as well as being lightweight and portable.
This is a great device to help you feel in charge of your health.
