Abstract
The invention relates to a gas measurement probe for determining at least one physical variable of a gas to be measured, in particular for determining the concentration of a gas component in an exhaust gas of an internal combustion engine, or for determining the temperature of the exhaust gas. The gas measurement probe as a housing with a thread, with which the gas measurement probe can be screwed into a counterpart thread of a measurement opening. On the housing, a region is provided, against which a tool can be positioned for screwing the gas measurement probe into the counterpart thread of the measurement opening. At least one annular groove is made in the region of the housing.
