The new cutting edge EasyOneT spirometer utilizes breakthrough ultrasonic flow measurement technology for fast, accurate and reliable operation. There are no moving parts, no codes to enter, no screens to catch sputum, and no disposables to calibrate. The device functions with a disposable

spiretteT which acts only as a hygienic shield and is transparent to the ultrasonic pulses traveling between the measurement transducers. Since the disposable spiretteT has no sensor elements, it does not perform a measurement function and does not require calibration. The EasyOneT stores up to

700 test sessions and EasyWare PC Software is available. EasyOneT meets ATS recommendation for diagnostic spirometry.
