    • An apparatus 24 (i.e. analytical smoking or vaping machine) for testing a tobacco heating product (THP) 1, comprising: means 32 for puffing the product 1; means 40 for sensing a temperature of a gas downstream of the product 1; and means 38 for generating a status signal indicating a heating status of the product 1 in dependence on the sensed temperature. The apparatus 24 may also remove particles from the aerosol drawn from the product 24, and/or capture particles for further analysis. The means 40 (i.e. thermocouple sensor, thermistor, resistance thermometer, silicon bandgap/optical/solid-state temperature sensor) may produce a temperature signal depending on the difference between the temperature of the gas stream and ambient temperature, wherein said temperature signal is compared to a threshold value. The control unit 36 may cease or modify puffing the product 1, and/or may output an alarm, in dependence on the status signal. The product 1 may comprise a tobacco heated stick 3 heated by an external electrical heating system, an internal electrical heating system, a sustainably self-heating tip (i.e. carbon tip), or by means of a chemical reaction.
