A method and apparatus for testing pressure applied to a smoking article is provided and is particularly useful in testing lip pressure applied to cigarettes. The system includes a pressure sensor adapted to be positioned on a predetermined portion of the smoking article that is to be subjected to external pressure. A pressure transducer is connected to the sensor. The output of the transducer responsive to the pressure applied to the smoking article and sensed by the sensor is displayed. Additionally, a method and apparatus for calibrating the pressure sensor is included. The calibration system includes a rigid enclosure and an elastomeric tube positioned in a recess in the enclosure and connected to a pressure regulator. The enclosure includes a recess conforming to the configuration of the smoking article with a pressure sensor mounted thereon and positioned so that the smoking article in the recess is in communication with the elastomeric tube so that when the tube is pressurized it exerts a measured contact stress on the smoking article and pressure sensor. Thus, the calibration can take place over a range of anticipated pressures.
