Zusammenfassung:PROBLEM TO BE SOLVED: To measure safely by preventing a main odor sensor from being deteriorated or damaged. SOLUTION: A presenser 22 which is less expensive and easily to replace than a main sensor 23 is set at an introduction path 13 before the main odor sensor 23. A flow path switch valve 18 arranged between the presensor 22 and main sensor 23 is operated based on measured results by the presensor 22, thereby preventing a sample gas of high concentration from entering the main sensor 23.
