How do I calibrate a CO₂ Sensor Foil SF-CD1R?

The SF-CD1R needs at least a four-point calibration with gas mixtures of different CO₂ content. We recommend gas mixtures with e.g. 1 % CO₂, 5 % CO₂, 10 % CO₂ and 30 % CO₂ in nitrogen.

Being in the field or working in small labs, a gas mixing system might not be available. In this case, you can use small and portable gas canisters and the respective accessories (valves, carrying bag, ...). These are obtainable at e.g. AirProducts.
