The pressure which a Specimen is exposed to locally.

The sample environment pressure sensor reading may differ from the actual pressure on the sample due to the complexity of the set-up and difficulty in calibrating the pressure measurement.

This is often the case for in-situ experiments where the sample is in a special sample holder, cryo box etc with a local pressure different to that of the rest of the chamber.

We are aware that sample environment pressure is typically only considered for in-situ experiments where the pressure is different to that in the rest of the chamber.
