The Invacare TruZone Peak Flow Meter makes it easy to monitor peak expiratory flowrates at home. The small size and shape enhance portability and ease-of-use. The unique logarithmic scale allows the TruZone to be used in low-flowrate conditions (pediatrics) or for standard flowrates. And through the use of ColorZone decals, each TruZone can be customized easily for color-zone management of asthma as recommended by the NAEPP (National Asthma Education and Prevention Program).

Features:

• Accurate measure of peak expiratory flow rates in low flows (pediatrics) and standard flows (adults)
• ColorZone decals easily customize the TruZone Peak Flow Meter for color-zone management of asthma.
• Meets the current American Thoracic Society Waveform for all 26 standards.
• Small size makes it easy to use or transport. 
• Clear body for easy reading of flowrate.
