| abstract |
The gas extraction system with an integrated two-stage pressure reducer for pressurized gas sources, the first and second regulating stages having a falling characteristic and preferably the pressure regulating devices being arranged opposite one another, has a very compact structure. The gas sampling system preferably contains a shut-off valve between the pressure control stages and is installed, for example, in compressed gas cylinders. The gas sampling system is particularly advantageously combined with a special protective cap. |
