Abstract:
Residual pressure and oxygen content of a pack are measured in an apparatus having a pressure measuring system and an oxygen measuring system in a branched arrangement. The oxygen content is measured by employing a vacuum pump to displace gas from the pack to an oxygen measuring system and a compression chamber which is then reset to atmosperic pressure and the oxygen content of the gas is measured. A two-way valve enables stopping displacement of the gas to the oxygen measuring system and enables the oxygen measuring system and compression chamber to be reset to atmospheric pressure.
