This multi-probe is a combination of a Prandtl tube and double slit TE measuring head with a shaft made of wound carbon. The TE head should be oriented upwards.Total pressure and static pressure follow the Prandtl geometry. This probe should only be tested for tightness using a vacuum, compressed air destroys the inner tubing! Caution: lightly lubricate the end piece to approximately 8cm before insertion and always insert the probe as far as it will go in.

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