Abstract

An exhaust gas measurement device includes a pressure regulator for keeping a pressure of sample gas in a sensor flow line or a bypass flow line to be a set pressure value, a flow rate sensor provided on the bypass flow line for measuring a flow rate of the sample gas flowing through the bypass flow line, and an attention attracting part for displaying that the flow rate of the sample gas is reduced in the case where the flow rate measurement value measured by the flow rate sensor becomes equal to or smaller than an attention attracting flow rate value larger than a pressure controlling limit flow rate value by a predetermined value, the pressure controlling limit flow rate value being a lower limit flow rate value that is pressure-controllable by the pressure regulator.
