A field olfactometer includes a mixing chamber connected to a mask. A sample flow path is defined through the olfactometer as is a diluent flow path. The sample flow path extends from a sample air inlet to a sample air outlet which is open to the mixing chamber. The diluent flow path extends from a diluent air inlet to a diluent air outlet which is also open to the mixing chamber. The sample flow path and diluent flow path are isolated from one another so that the sample air flowing through the sample flow path and diluent air flowing through the diluent flow path cannot mix until the two streams of air exit their respective flow path and enter the mixing chamber where the two streams mix thoroughly prior to reaching the mask. The diluent flow path includes a filter medium to remove odor-causing chemicals from ambient air drawn through the diluent flow path. A flow indicator arrangement provides a suitable indication when the flow rate at one or more points in the olfactometer reaches a predetermined value corresponding to a target dilution of diluent air to sample air. Different flow characteristics along the sample flow path as compared to the diluent flow path produces a gradually decreasing dilution ratio as a user inhales nasally at an increasing rate through the mask.
