Air flowDigital thermo-anemometer omnidirectional FVAD 05-TOKx, with ALMEMO® D6 plug, with integrated atmospheric pressure sensor for automatic atmospheric pressure compensation Technical data and functions • Omnidirectional sensitive tip with exposed heat ball probe. • Optimized version for measuring low flow velocities in air. • Solid construction of the sensor top, suitable for mobile usage. • Digital thermo-anemometer with integrated A/D converter in the ALMEMO® D6 plug. • Automatic atmospheric pressure compensation of the flow velocities dependent on the atmospheric pressure with digital atmospheric pressure sensor integrated in the ALMEMO® D6 plug. Alternatively manual input of the atmospheric pressure in the ALMEMO® D6 sensor menu. Two measuring channels are preprogrammed on leaving our factory: flow velocity (m/s, v), atmospheric pressure (mbar, AP, p).
