Abstract

A smoking machine includes, for controlling the conditions in which each article to be smoked is smoked, only a servo-control device for controlling, to a reference value, the pressure difference between the suction end and the rest of the body of the cigarette. The support of each article is mounted for rotating so as to allow, for example, more accurate detection of the position of the incandescent zone by optical sensors and a processing circuit.
