Abstract
A measuring device is disposed against a medium, the device extending between a contact face applied facing the medium and a distal end, and including a lateral wall extending between the contact face and the distal end. The device includes: at the level of the contact face, an admission opening through the contact face collecting a transcutaneous gas of interest emitted through the medium; a measuring chamber including a gas sensor measuring a concentration of the gas of interest flowing through the measuring chamber; and a collecting chamber connected to the measuring chamber and delimited by an opening on the lateral wall, the collecting chamber including a lateral opening admitting a vector gas into the collecting chamber. The measuring chamber is disposed between the contact face and the collecting chamber. The device includes a pump driving a vector gas through the collecting chamber to an evacuation opening.
