Stupid question: How to you ensure that the steam is saturated,
while keeping a constant pressure?
I think just buying some indium off ebay and use that as a melting/freezing
reference is easier than the contraption needed to ensure fully saturated
steam, with a low temperature gradient over the temperature sensor.
That said. My investigations into stability of PT100 sensors reveal,
that the quality ones can be less than 10mK/year, but hysteresis is
in the same ball park (see [1]).
