An olfactometer is disclosed. Such an olfactometer may include a control unit, an odor box, and a nose piece in communication with the odor box. The control unit may include a reservoir, and a compressor for supplying pressurized air to the reservoir. The odor box may include at least one compressed air actuated valve, and at least one odor canister in communication with the valve. A compressed air flow and a breathable air flow are both released from the reservoir and directed to the valve. The compressed air flow actuates the valve to thereby direct the breathable air to the odor canister to odorize the breathable air. The odorized breathable air is then directed to the nose piece.
