Pitot tube: 335 mm, Ø 8 mmWeight (including pitot tube, battery and measuring hoses)600 g  

The Pitot tube anemometer has a thread on the underside so that it can be mounted on a tripod. The measuring hoses are attached to the top of the Pitot tube anemometer and can thus be connected to the Pitot tube.
