Abstract
A device determines an oxygen content of a headspace gas in a liquid-filled container. The device contains a piercer, a sampling tube, a piercing head on which the piercer and the sampling tube are disposed, a pump, a ring line, and a sensor unit disposed within the ring line and used to determine the oxygen content and/or an oxygen partial pressure of the headspace gas of the liquid-filled container. The ring line is configured such that the headspace gas of the liquid-filled container can be sampled via the piercer or the piercing head by use of the pump and can be returned into the headspace of the liquid-filled container via the sampling tube.
