Olfactometers are devices built to present odor stimuli in a standardized computer-controlled manner with determined air flow, odor concentration, odor duration, onset, and offset. Sometimes even humidity, temperature, and other features can be controlled. The olfactometer regulates the gas flow (0.5 L/min), and switches flow between clean air and air with an odor by passing the air through a bottle containing eugenol. The olfactometer, connected to the test cage (25 x 37 x 24 cm), can supply either the clean air or the odor through the gas port (0.5-mm diameter hole) on the wall (2-cm height).
