Electronic Peak Flow Meter Pempa PF200A
Measurement range: 60–800 l/min BTPS
Accuracy: 10 l/min or 10% of the measured value (whichever is greater)
Repeatability: 5 l/min or 5% of the measured value (whichever is greater)
Storage environment: 10–35 °C, 30–75% relative humidity
Maximum resistance: 0.00384 kPa/L/min at 720 L/min
Height of the peak flow meter (and exhaled air): The device reduces the measurements by approximately 5% at 1000 m altitude (decrease in air density – PEF increases by about 5% at 1000 m altitude)
Frequency range: The A/B profile difference is less than 15 liters/minute or 15% (whichever is greater).
