A Kiel probe is a device for measuring stagnation pressure or stagnation temperature in fluid dynamics. It is a variation of a Pitot probe where the inlet is protected by a "shroud" or "shield." Compared to the Pitot probe, it is less sensitive to changes in yaw angle, and is therefore useful when the probe's alignment with the flow direction is variable or imprecise.<ref>Template:Cite book</ref>
