A leak detection device and method for use in testing a wall with selective gas/liquid permeability. The wall is sealed inside a containment including an injection chamber and a test chamber. The injection chamber is in communication with an injection and pressurization source and the test chamber is in communication with a vacuum production device. A vaporized liquid detector is in communication with the test chamber operable to detect and/or measure a parameter related to a quantity of liquid vapor or a variation in the quantity of liquid vapor which is indicative of a leak condition through the wall.
