Abstract
In order to provide an exhaust gas measurement apparatus having a simpler configuration capable measuring a concentration of a predetermined component contained in exhaust gas under various situations without deteriorating a measurement accuracy, there is provided a sampling mechanism that can select any one of two states, i.e., a first operation mode for outputting the sampled exhaust gas without dilution and a second operation mode for outputting the sampling exhaust gas mixed with dilution gas. In a situation where the sampling mechanism is operating in the first operation mode, in the case where the concentration of the predetermined component measured by a measurement apparatus body exceeds a predetermined first threshold value, the sampling mechanism is controlled such that the first operation mode thereof is changed to the second operation mode.
