Will an unsuccessful measurement be counted by the sensor?

The NIOX VERO® is designed to produce an accurate result each time, every time, throughout the life of the sensor. An unsuccessful exhalation will not be counted as a measurement. The device display will show alert codes A10 to A13 if the test has been interrupted and the patient should be asked to repeat the process.
