A sealed sensor housing for use in measuring the concentration of an additive or impurity in gasoline comprises a housing body of metal formed by a deformation process with no substantial machining, and the housing body is joined together with an inlet tube, an outlet tube and an electrode such that the electrode is hermetically sealed in the housing body. The deformation process may be hydroforming, deep drawing, coldforming, forging or stamping. |
