Abstract

To solve a leakage problem in a box, it is proposed to provide the box with an electronic circuit for measurement of its specific humidity. It is shown that by comparing this current specific humidity to an initial specific humidity and by evaluating the difference found in relation thereto, one has a reliable tool for measuring the permanence of tightness.
