A stench measuring device equipped with a preprocessor, and a difference calculating method and an expected stench intensity calculating method by using the same are provided to correctly measure stench in a predetermined condition by correcting a state of an air sample into a predetermined condition and measuring the stench from the corrected air sample. A main inlet(100) receives sample air and a main outlet discharges the sample air to the outside. A stench measurer(400) is placed between the main inlet and outlet, and measures a stench state of the sample air. The preprocessor(200) is placed to a rear side of the main inlet and preprocesses the sample air flown in the stench measurer into the desired state. The stench measurer includes stench sensors(430a,430b) installed to the inside of the stench measurer and a numeric analyzer(500) analyzing a value measured in the stench sensor. The preprocessor includes a state measurer(210), a state corrector(220), a clean air supplier, and a controller(230). The state measurer includes a temperature sensor(211) and a humidity sensor(212). |
