Microlife Digital Peak Flow Meter (PEF) and Forced Expiratory Volume (FEV1)

The Microlife Digital Peak Flow Meter with FEV1 is the doctor's choice for managing diseases that restrict lung performance. This advanced meter for spirometry includes a digital diary and measures air flow velocity and volume (FEV1) to indicate early warning signs for impending asthmatic incidents or conditions. Using these measurements in conjunction with a doctor's consultation allows patients with asthma, COPD and other lung diseases to manage their condition.
What is PEF: PEF is Peak Expiratory Flow, or in other words measures how fast you can push air out of your lungs.
What is FEV: FEV is Forced Expiratory Volume, or in other words measures how much air a person can exhale during a forced breath.

| Peak Flow readings: Range | ± 0.1 or 50 to 900 l/min. |
| FEV1 readings: Accuracy | ± 0.1 or ± 5% of the reading, whichever is greater |
