| 摘要 |
<p>The invention provides a combustion exhaust analysis device enabling a measurer to identify errors of measurements of a CO2 sensor. An operation processing part (32) comprises an operation unit (34), a correcting unit (36), a correlativity data hold part (37), a carbon dioxide concentration presumption unit (38) and a carbon dioxide concentration error presumption unit (40). The correlativity data hold part (37), the carbon dioxide concentration presumption unit (38) and the carbon dioxide concentration error presumption unit (40) are used for evaluating the accuracy of the measurement of carbon dioxide concentration used in correcting of component concentration of a measurement target by the correcting unit (36). In order that the accuracy of the carbon dioxide concentration of sample gas obtained according to a signal acquired by the CO2 sensor (14) can be judged, the measurement of an O2 sensor (24) in the device is used.</p> |
