Abstract
An apparatus is provided for determining the burning and/or glowing rate of a smokable article. The apparatus comprises a sensor for sensing the incandescent zone of the smokable article and a drive apparatus for moving the sensor along a path parallel to the direction of burning and glowing of the smokable article. A control circuit, including first switches is coupled to the sensor and the drive apparatus, for stopping the drive apparatus and thereby the movement of the sensor when the sensor detects a predetermined radiation intensity and for starting the drive apparatus and thereby the sensor when the sensor detects a radiation intensity other than the predetermined intensity when the first switches are in a first state and for starting the drive apparatus and thereby the movement of the sensor means when the sensor detects a predetermined radiation intensity and for stopping the sensor when the sensor detects a radiation intensity other than the predetermined intensity when the first switches are in a second state.
