A self-contained mobile apparatus which replicates the evaluation of scents, fragrances, aromas and odors in controlled and home environments. The apparatus simulates various stages of the consumer experience and has adjustable settings for dosing, air flow, and room size. The scented compound sample is placed within a cabinet having an enclosed sample chamber which is connected to an upward facing sample tube. An air fan is mounted within the sample chamber which circulates and controls sample air flow upward to a testing station wherein the sample air flow is tested for the identification and the concentration of the scent contained therein. A return air chamber and filter are mounted below the testing station. The filtered return air is controlled downward by a return air blower to provide an exhaust out through the bottom of the apparatus.
