Air velocity displayed on the instrument is calculated at fixed conditions: L Pitot tube with a deprimogen coefficient of 1.0015, at 20°C (68°F) and 1013.25 hPa (29.92 inHg). When the app is used to display air velocity, these parameters can be modified.
*All the accuracies indicated in this technical datasheet were stated in laboratory conditions and can be guaranteed for measurements carried out in the same conditions.
**Calculated values, only available on the app
