A chamber for producing smoke having particular application for detecting and locating leaks in a fluid system. Sealed within a smoke producing chamber is a supply of fluid that is adapted to be vaporized into smoke. An air inlet tube having an inlet orifice runs through the supply of fluid. When air is pumped through the air inlet tube, some of the fluid is drawn via the inlet orifice into the tube and blown against a heating element that extends laterally across the chamber above the supply of fluid, whereby the fluid is vaporized into smoke. The smoke exits the chamber through an air outlet tube so as to be introduced, by way of a flexible smoke supply conduit, to the system to be tested.

[ We claim:] [1.] Apparatus for generating smoke, comprising:a smoke producing chamber;a supply of fluid located within said smoke producing chamber to be vaporized when heated;a heating element located within said smoke producing chamber above said supply of fluid;an air inlet communicating with said smoke producing chamber to receive air under pressure, said air inlet having an inlet orifice in fluid communication with said supply of fluid so that when air under pressure is delivered through said air inlet, some of said supply of fluid is drawn into said air inlet via said inlet orifice, whereby a mixture of air and fluid is blown through said air inlet and against said heating element to be vaporized into smoke when said heating element is heated; andan air outlet to permit said smoke to exit said smoke producing chamber.
