An exhaust gas measurement device, comprising: an introduction flow line to which sample gas containing exhaust gas is introduced; a sensor flow line branched from the introduction flow line and provided with at least one gas analyzer for measuring components contained in the sample gas; a bypass flow line branched from the introduction flow line so as to bypass a part of the sample gas; a pressure regulator adapted to keep a pressure of the sample gas in the sensor flow line or the bypass flow line to be a set pressure value; characterised in that the device further comprises a flow rate sensor provided on the bypass flow line and adapted to measure a flow rate of the sample gas flowing through the bypass flow line; and an attention attracting part adapted to display that the flow rate of the sample gas is reduced in the case where a 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, wherein the at least one gas analyzer is configured to continue measuring after the attention attracting part displays the flow rate of sample gas is reduced. an introduction flow line to which sample gas containing exhaust gas is introduced; a sensor flow line branched from the introduction flow line and provided with at least one gas analyzer for measuring components contained in the sample gas; a bypass flow line branched from the introduction flow line so as to bypass a part of the sample gas; a pressure regulator adapted to keep a pressure of the sample gas in the sensor flow line or the bypass flow line to be a set pressure value; characterised in that the device further comprises a flow rate sensor provided on the bypass flow line and adapted to measure a flow rate of the sample gas flowing through the bypass flow line; and an attention attracting part adapted to display that the flow rate of the sample gas is reduced in the case where a 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, wherein the at least one gas analyzer is configured to continue measuring after the attention attracting part displays the flow rate of sample gas is reduced. a flow rate sensor provided on the bypass flow line and adapted to measure a flow rate of the sample gas flowing through the bypass flow line; and an attention attracting part adapted to display that the flow rate of the sample gas is reduced in the case where a 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, wherein the at least one gas analyzer is configured to continue measuring after the attention attracting part displays the flow rate of sample gas is reduced.
