The invention relates to simple and inexpensive equipment based on a hygrometric sensor formed by an electrical salt bridge, functioning in a linear manner and within the range of milliseconds. In order to permit a flexible use, particularly in intensive care, this sensor is located at the distal end, with respect to the face of the subject, either of a catheter, advantageously with nasal insertion, or of an oronasal mask with a single or double opening, the morphology of which mask is, in one of the models of the invention, formed by a truncated cone facilitating the serial deposition of the salt bridge.
