ABSTRACT:
A detection device with a gas detector element for analyzing pressurized gases contained in a reservoir by sampling while the pressure is reduced. A coupling means is provided for connecting the detector to a reservoir. Ease of handling is facilitated in the routine operation by providing a time-keeping device determining the duration of the sampling flow set at a preselected value. A switch starts the time-keeping device, and the switch is actuated at least at the time of the coupling of the detector to the reservoir.
