This multi-probe is a combination of a Prandtl tube and double slit TE measuring head. All parts are made of nickel-plated brass which makes it more robust but heavier than the carbon multi-probe. The TE head should be oriented upwards. 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.
