Btw. Where are the mV values stored?
And are there any fO2 calibration gas value stored anywhere?
The calibrations are done as a single point calibration, eg. This sensors gives a mV response of X for a known gas with a fO2 of Y at pressure Z.
From that the sensor is assumed to give a linear mV response to
different ppO2's.
