Verification system

A reference gas supply part that is used for an exhaust gas analysis system comprising:

• an exhaust gas dilution device adapted to mix exhaust gas and diluent gas to produce diluted exhaust gas having a predetermined setting flow rate;
• and an analyzer adapted to measure a component contained in the diluted exhaust gas, and a component part of a verification system configured to be able to verify consistency between a supply amount of reference gas supplied in place of the exhaust gas and a measured value of the reference gas, the measured value being measured by the analyzer,
• the reference gas supply part supplying the reference gas so as to meet a target supply amount on a basis of a control signal from a control part that receives a setting flow rate signal that is a signal indicating the setting flow rate and an analysis range signal that is a signal indicating an analysis range of the analyzer and calculates the target supply amount of the reference gas on a basis of the setting flow rate and the analysis range indicated by the respective signals.

A recording medium recorded with a verification program applied to a verification system that is used for an exhaust gas analysis system comprising:

• an exhaust gas dilution device adapted to mix exhaust gas and diluent gas to produce diluted exhaust gas having a predetermined setting flow rate;
• and analyzer adapted to measure a component contained in the diluted exhaust gas, and configured to be able to verify consistency between a supply amount of reference gas supplied in place of the exhaust gas and a measured value of the reference gas, the measured value being measured by the analyzer,
• the verification program instructing a computer to fulfill a function of a control part that receives a setting flow rate signal that is a signal indicating the setting flow rate and an analysis range signal that is a signal indicating an analysis range of the analyzer, calculates a target supply amount of the reference gas on a basis of the setting flow rate and the analysis range indicated by the respective signals, and performs control so as to make the supply amount of the reference gas equal to the target supply amount.
