Abstract: A method for measuring topographical information to provide smoking topographical information including providing a portable smoking topography measurement unit having a smoking material holder; inserting a smoking material into the smoking material holder of the portable smoking topography measurement unit; detecting each puff of the smoking material; measuring flow rate of smoking from a smoking material into a subject during each puff; computing puff information; eliminating false puffs from the puff information; computing smoking material information; and storing puff information and smoking material information in a memory. The puff information and smoking material information is transferred from the memory of the portable smoking topography measurement unit to a workstation, and the puff information and smoking material information is displayed on a display unit.

Abstract: A portable smoking topography apparatus for providing smoking topographical information, comprises a smoking material holder adapted to receive a smoking material; a smoking material detection sensor mounted on the smoking material holder and detecting presence or absence of a smoking material; a puff sensor detecting a puff of the smoking material by a subject; a clock; a computing unit coupled to smoking material sensor and the puff sensor, wherein the computing unit reads start time and end time of each puff from clock, reads sample flow rates of smoke from the smoking material during each puff, reads time of insertion of smoking material and time of removal of smoking material from clock as detected by smoking material detection sensor, calculates puff information. The computing unit calculates smoking material information. The portable smoking topography apparatus transfers at least one of puff information and smoking material information to a workstation.
