This multi-probe is a combination of a Prandtl tube and Venturi nozzle with a shaft made of wound carbon. The TE head should be oriented upwards. Total pressure and static pressure follow the Prandtl geometry. Caution: lightly lubricate the end piece to approximately 8cm before insertion! Compressed air destroys the inner tubing.

Note: Images and drawings are similar. Certain differences are caused by manual production or further development.
