| 説明 | On the IC 3 from Chur to Basel just before Sargans. Air measurement in a conventional train with standard cars IV and locomotive. The car was full and the air conditioning on. The ventilation was practically inaudible and the subjective perception of the air quality was good. The outside temperature was 22°C. The critical limit value for CO2 pollution is specified differently. With this device it is 1200 ppm. Recommended levels range from 1000 ppm to 1400 ppm for acceptable indoor air. In this case, it's a good value for a full car. My experience so far has shown that older rolling stock usually achieves better CO2 values than modern multiple units. Switzerland, July 7, 2022. |
