• Is used to measure peak expiratory flow rate (PEFR), an important indicator of your lung function.
• Peak Flow Meter should be used for monitoring respiratory conditions such as asthma.
• Taking peak flow measures every day and keeping a record of the peak flow measures in your “peak flow diary” can help you and your physician make important decisions about your treatment.
• This meter was designed to make following your asthma treatment plan easy.

Specifications:

Measurement Range: PF120 A : 60-800 L/min BTPS, PF120 C: 50-400 L/min BTPS
Accuracy: ± 10 L/min or ± 10% of reading (whichever is greater)
Repeatability: ± 5 L/min or ± 5 % of the reading (whichever is greater)
Storage Condition: 10-35 oC, 30-75% RH
Max resistance: 0.00384 kPa/L/min@ 720 L/min
Altitude effects on the Peak Flow Meter (and on the expired air): Lowers readings by approx. 5% per 1000m, (decreased air density increases PEF by approx. 5% per 1000m)
Frequency response: Profile A/B difference less than 15 L/min or 15% (whichever is greater)
