Abstract
A portable, hand-held combination smoke machine and nitrogen generator having particular application for supplying a mixture of smoke and inert, non-combustible nitrogen gas to a closed fluid system (e.g., the evaporative or air brake system of a motor vehicle) so that the presence and location of a leak can be detected. The nitrogen generator is preferably a compact, commercially-available nitrogen generating membrane tube that is sized to be grasped and lifted in the hand of a user. The smoke machine has a smoke generator device that is adapted to produce smoke and is coupled to the nitrogen generating membrane tube so that a supply of nitrogen gas is delivered from the tube to the smoke generator device at which to be mixed with smoke. The nitrogen gas carries the smoke outwardly from the smoke generator device of the smoke machine to the system being tested for leaks.
