<p>The invention relates to a device for measuring the resistance-to-draw of a smoking article having a mouth end and a rod end, the device comprising a chamber having an opening for receiving a smoking article, a first sleeve and a second sleeve for holding the smoking article and defining a space between the first sleeve and the second sleeve, a first aperture in a wall of the chamber for introduction of air into the space and a second aperture for extraction of air passed through the mouth end of the smoking article for determination of resistance-to-draw, characterised in that the opening is selectively closable to prevent air flow through the rod end of the smoking article. This enables resistance-to-draw of a smoking article to be measured without flow of air along the entire length of the smoking article.</p> |
