1) Prolonged operation below 0.1% O2 can damage the sensing element.
2) Assuming barometric pressure remains constant.
3) As the O2 sensor measures the partial pressure of oxygen within the measurement gas, deviations in the barometric pressure from that present during calibration will cause readout errors proportional to the change.
Example: If the sensor reads 21% O2 at 1013.25mbar and the barometric pressure increases by 1%, the sensor readout will also increase by 1% to 21.21% O2
