Page 11: Considerations
The final OTR result obtained from a test using either atmospheric oxygen (i.e. air) or pure oxygen will be identical. This is because the algorithm employed by OxySense to calculate OTR yields a result that is normalized to the oxygen concentration in the bottom of the chamber. -
