    摘要: The invention relates to a measuring device (1), preferably a test stand for engines and vehicles for analyzing exhaust gases of a combustion engine (2), comprising at least one exhaust gas supply line (3, 4), which can be connected to the exhaust system of the combustion engine (2) and which supplies at least one measuring branch (7, 8, 9) each provided with a respective analysis unit (12, 13, 14) for determining exhaust gas constituents. According to the invention, a filter device (16a to 16f) is provided in at least one cool measuring branch (9) upstream from the analysis unit (14) and/or between different components (14a, 14b) of the analysis unit (14) and/or on the output side of at least one analysis unit (12, 13, 14) of one of the measuring branches (7, 8, 9). This filter unit contains a filter material that is selective with regard to gaseous hydrocarbons, preferably a filter material selected from the group consisting of zeolites and/or silicates.
