A spray device for detecting leaks is provided, including: a duct including an inlet configured to be connected to a tracer gas source, and an outlet; a valve interposed between the inlet and the outlet; a casing receiving the duct and the valve; at least one probe arranged in the duct, the at least one probe being configured to measure a parameter revealing a presence of the tracer gas in the duct; and at least one information device borne by the casing, configured to provide information on the presence of tracer gas in the duct in relation to a measurement performed by the at least one probe.

Spray device and leak detection module

A leak detection module for checking the seal-tightness of an object to be tested by tracer gas is provided, including a leak detector and a probe configured to be manipulated by a user; and a vision device including a processing and display unit configured to communicate with the leak detector, a securing means configured to secure the vision device on a head of the user, and a viewing surface fixed to the securing means and configured to be placed in a field of view of the user, the processing and display unit being further configured to display, on the viewing surface, information relating to detection of leaks including at least one signal representative of a concentration of tracer gas measured by the leak detector. A method for checking the seal-tightness of an object to be tested by tracer gas is also provided.
