| 摘要 |
The invention relates to a gas analyser (2), comprising a test chamber (8) for a gas sample, an inlet (6) for the gas sample and a gas sensor (16) sensitive to gas movement, for determining the concentration of a constituent gas in the gas sample. The inlet (6) is adapted to be connected to an inspiration line (22) of a respirator (18). When a shielding means (12) is arranged so it covers the inlet (6) of the test chamber (8), the gas sample remains relatively still inside the test chamber (8) during the analysis, regardless of the flow of the gas to be analysed. The gas analyser (2) can accordingly be devised for direct connection to the gas to be analysed. <IMAGE> |
