I summarise below the emails received regarding Carbon Dioxide sensor suppliers. Many thanks to those who responded. 1: Our institute has developed a gas sensor, which enables measurement of high doses of carbon dioxide in dry air. You can see it's principle if you follow our homepage http://141.30.124.127. Is is not commercially available. However, our partner company (Aktiv Sensor, Ruhlsdorfer Str. 95, Gebaeude 5A, 14532 Stahnsdorf, Germany) thinks about production of prototypes in the next time.
