ccurately measuring the patient ultrasonic test pulmonary function testing

Our speical point:

1. Contact –free measuring , sensitive &durable

2. Resistance-free airway, difficulty –free measuring for low /high airflow

3. Direct flow measurement, wide linear range, no linear distortion

4. Calibration free

5. No direct contact with the airflow, vapor-free, replacement & cleaning free

6. Ergonomic and independent design of the airway to effectively eliminate cross-infection
