Abstract
An apparatus that is configured to sense the presence of gases, vapors and liquids using acoustic waves. The apparatus comprises a first part that is configured to generate acoustic waves. The apparatus further comprises a second part having a sensing and acoustic wave guiding device, which is configured to sense the presence of such substances and propagate acoustic waves. The first part is removably fixable to the second part of the apparatus. When the first part is fixed to the second part, the acoustic waves propagate in the second part.
