Breathing Test Lung

PinYuan LUD-V2 portable pulmonary function tester specificationsThe most advanced differential pressure flow sensor is employed in the development and production of the pulmonary function tester. The user's expiratory flow signal is obtained through three measurement methods: slow vital capacity (SVC), forced vital capacity (FVC), and voluntary ventilation (MVV). The results are then calculated and evaluated to provide a scientific foundation for the early screening and diagnosis of respiratory diseases, including chronic obstructive pulmonary disease (COPD), emphysema, and asthma..This measurement method is more precise and efficient. More practical.Product Specifications1. Method of measurement: differential pressure flow test

2. Sensor: High-precision double differential pressure flow sensor3. Flow measurement range: 0L/s to ±14L/s

4. Flow measurement error: The maximum allowable flow error in the measurement range is ±10L/min (±0.17L/s) or ±5% of the reading.5. The volume measurement error is ±3% or ±0.050L, whichever is greater, within the range of 0-8 L.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 test flow change does not exceed 0.17L/S or 5% of the reading, and the average error of two adjacent test flows does not exceed 5% of the two test flows.9. Pulmonary function measurement: voluntary ventilation (MVV), forced vital capacity (FVC), and slow vital capacity (SVC) can be assessed.
