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. |
