Abstract

The subject of the invention is a probe for detecting leaks of a tracer gas through a wall of a container, more particularly dedicated to the detection of leaks in an aircraft tank. Said probe comprises a body (18) that includes a sensor (32) for sensing the tracer gas used, and means (34) for dynamizing the flow striking said sensor so as to concentrate and accelerate the tracer gas before it comes into contact with this sensor.
