Product Parameters
1.  Measurement method: differential pressure flow test method
2.  Sensor: High precision double differential pressure flow sensor
3.  Flow measurement range: 0L/s ~ ±14L/s
4.  Flow measurement error: The maximum allowable flow error in the measurement range should be: ±10L/min (±0.17L/s) or ±5% of the reading
5.  Volume measurement range: 0-8 L volume measurement error: ±3% or ±0.050L, whichever is the maximum
6.  Airflow resistance: The airflow resistance within the test range should not exceed 0.35KPa/ (L/s)
7.  Frequency response: no more than 0.25L/s or 12%
8.  Linearity: the difference of the average error of two adjacent test flows does not exceed 5% of the two test flows, and the test flow change does not exceed 0.17L/S or 5% of the reading
9.  Pulmonary function measurement: forced vital capacity (FVC), slow vital capacity (SVC), and voluntary ventilation (MVV) can be measured.
10.  Lung function measurements were guided by animation.
11,Measurement parameters:FVC,FEV0.5,FEV1,FEV3,FEV1/FVC,PEF,MEF75,MEF50,MEF25,MMF, OI,FIVC,PIF,FIV1;VC,TV,ERV,IRV,IC,VC/HT;MVV,RR,MVV/BSA,TV,BSA .
12.  Volume-flow velocity curve and time-volume curve were generated according to the pulmonary function measurement results.
13.  Unique filter and mouth design, more tightness, prevent air leakage during measurement.
14.  It has the function of COPD assessment and ventilation defect assessment.
15.  System software functions: instrument zero and calibration function, doctor management system, history review system, medical record review function, user file management function.
