Air Flow** m3/h, m3/min, m3/s, cfm from 0 to 9999 m3/h 1 m3/h / 0,001 m3/s / 0.01 m3/min / 0.1 ft3/min
Air Velocity*** m/s, fpm from 2 to 80 m/s from 394 to 15748 fpm 0.1 m/s 1 fpm

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.
