In this study, odors in N industrial complex in Incheon city were measured by using air dilution olfactory method, odor sensor and instrumental analysis method. Three industry categories which are plating industry, equipment manufacturing industry and petrochemical manufacturing industry were classified and the correlation of data was evaluated based on the measurement result. The correlation coefficient between the air dilution olfactory method and the odor sensor device utilizing method in 69 points was 0.562. The correlation coefficients in the classified industry categories were observed 0.889 in the plating industry, 0.723 in the equipment manufacturing industry and 0.832 in the petrochemicals manufacturing industry. It shows that when the correlation coefficient is over 0.75, they have a strong correlation. In this result, we could identify the ease of availability of the correlation using industry classification.
