Method for checking the sealing of an object and leak detection device

The invention relates to a method for checking the sealing of an object (11) to be tested by tracer gas using a probe (3) of a leak detection device (1) and comprising the step intended to scan the outer surface of the object (11) using the probe (3) in order to successively record, in a processing module (7) of the leak detection device (1), several values representative of the tracer gas leak rate measured by the detection device (1), each value representative of the tracer gas leak rate measured being associated with a value representative of the location of the probe (3) and the step intended to graphically represent, on a display element (9), the associated values recorded during the scanning of the outer surface of the object (11).
