This sort of speculation over simple facts is frustrating. It's really too bad Dr. Levi didn't give the pump make and model in his report. > You're also right about the probes, but it's possible in that case > that the RH probe was simply not in place when the photo was made.

The explanation which has been given in this forum is that the so-called RH probe actually measures the capacitance of the air, and that, in turn, can be used to measure the wetness of steam just as easily as the RH of air. The remaining problem with that explanation is the issue of whether the capacitance probe used is accurate enough to assure that the steam really is dry. I seem to recall Horace had some concerns about that.
