1889H. Zwaardemaker in Lancet 29 June 1301/1, I have lately constructed a small instrument which, I think, deserves the name of ‘olfactometer’. Its component parts consist of two tubes fitting into each other. The outer one is lined with scented material, and made to glide up and down over the inner one, of which one end remains free and is bent to fit the nostril. 1922G. H. Parker Smell, Taste & Allied Senses iii. 51 Two single olfactometers may be combined so that one current carrying an odorous material..may be introduced into one nostril and another carrying a second odorous substance..into the other nostril. 1969J. R. Hughes et al. in C. Pfaffmann Olfaction & Taste 173 Stimuli have been presented by a portable two-channel olfactometer. 1969Daily Tel. 9 Sept. 20/8 He has developed devices, known as olfactometers, which at present measure only the intensity of odours but do not differentiate between them.
b. A device for investigating the responses of animals to odours.
1926Jrnl. Econ. Entomol. XIX. 552 Adult potato beetles were collected in potato patches and were tried in the insect olfactometer. 1969New Scientist 17 Apr. 134/2 Some initial experiments using an olfactometer suggested that the sense of smell did not play any part in bringing the male and female spiders together. |
