The colour coded indicators define three zones which make it simple for the user to know what percentage of their peak flow they are achieving. Personal Best is simple to use and store.
The fold-out handle keeps the hand away from the airstream, aiding good technique for an accurate reading, and also forms part of the protective casing.
3-Zone Asthma Management is colour coded to make it clear for user Green zone 80 – 100% of personal best Yellow zone 50 – 80% of personal best Red zone 50% or less of personal best
