Why use ultrasonic spirometer?
No calibration with ultrasonic technology
The spirometer is equipped with ultrasonic gas flow sensor, which can measure body’s respiratory function and inspiratory function. It converts the patient breathing signal into electrical signal sending the electrical signal to the corresponding signal processing circuit, then calculates a variety of physiological parameters. Then through the analysis, processing, LCD display and printing, the results can become the doctor's diagnosis reference.
For the spirometers with the pressure difference sensor and turble type gas flow sensor, they need the frequent calibration for a good precision. The reason why we use the ultrasonic gas flow sensor is for no calibration anymore for using on site. In comparison, ultrasonic is the best technology for handheld spirometer and it is durable.
Ultrasonic technology key features
■No calibration anymore for using on site.
■The results are reliable and precise.
Cubic Ultrasonic Spirometers can be widely applied for hospital, community and family use.
