Abstract
Micro-leaks are detected by means of a sniffer device including, in an original manner, a flat suction capsule () with divergent channels where the flow is regular, a resonant optical cavity () as a means of detection and a pump () with a low flow rate, which is insufficient to create a vacuum which would be required with other means of detection. Much fainter micro-leaks can be detected.
