摘要： An apparatus for evaluating an oxygen sensor includes a device for mixing a fuel and an oxygen-containing gas in an appropriate ratio to prepare a fuel mixture. A burner is connected to the mixing device for burning the fuel mixture to produce a gaseous combustion product. A tubular member extends from the burner for supplying the combustion product. A nozzle is connected to the tubular member for introducing a fuel and an oxygen-containing gas into the tubular member so that the combustion product is of a desired excess air ratio (air-fuel ratio) and a mounting device for the sensor to be evaluated is disposed on the tubular member, downstream of the nozzle.

摘要： The invention relates to a method of producing a gas sensor element having a porous film formed by a thick-film technique on a ceramic substrate surface so as to cover selected portions of electrode films precedingly formed on the substrate surface. The electrode material is a noble metal such as platinum. Both the electrode films and the gas sensitive porous thick-film are formed by known methods. To improve the contact between the gas sensitive porous thick-film and the electrode films both mechanically and electrically and stabilize the internal resistance of the sensor element by depositing a noble metal such as platinum at the interface between the porous thick-film and each electrode film, the porous thick-film is impregnated with a solution of a noble metal compound such as chloroplatinic acid and thereafter maintained in a reducing gas atmosphere having a controlled humidity in the range from 5 to 90% (relative humidity) at a temperature in the range from 10.degree. C. to 135.degree. C.
