<P>PROBLEM TO BE SOLVED: To provide an exhaust gas measurement device and a program for the exhaust gas measurement device that allow a user to predict a time when pressure regulation by a pressure regulator becomes impossible and exhaust gas measurement is impossible to be continued before these occur and can prevent interruption of measurement during the measurement by performing maintenance of a filter and a pump, etc. before the measurement completely becomes impossible. <P>SOLUTION: The exhaust gas measurement device includes: a pressure regulator 331 for keeping pressure of sample gas in a sensor flow channel 32 or a bypass flow channel 33 at a set pressure value; a flow rate sensor 332 provided in the bypass flow channel 33 to measure flow rate of the sample gas flowing in the bypass flow channel 33; an attention calling section 41 for displaying that the flow rate of the sample gas is dropped when a flow rate measurement value measured by the flow rate sensor 332 becomes an attention calling flow rate value or less, which is a flow rate value larger by a prescribed value than a pressure regulating limit flow rate value to be a lower limit flow rate value which can be regulated in pressure by the pressure regulator 331. <P>COPYRIGHT: (C)2013,JPO&INPIT |
