Why does a hot data logger read a pressure different from one at room temperature?

The pressure is related to the temperature and we correct the two parameters with the calibration. Given the metal mass of the data loggers and their slow cooling after leaving the autoclave, it may be that the ambient pressure detected by this device in cooling, therefore with variable temperature, is slightly different from the ambient pressure of a device that is located at stable temperature. When the logger stabilizes its temperature, the pressure detected by the two loggers must align.
