For humidity to get thru something like that it takes weeks or more it
does it at all.
That fast of reaction, Sure sounds like some other effect like blowing a
little air on the case or loading the osc output with water in the
output cable etc, etc.
I think it is safe to say the effect was not due to water inside, unless
there was a hole.

The effect we saw was like parts in 10^8 of something. Way too big
to be related to output loading or air on the case. In any event,
the air blowing on the case was constant during the test.
We saw that when we didn't even try to seal the 10811 and also
when we tried to seal it.
Blowing on the case? Did you consider the increased cooling that higher
humidity provides?
Cheers,
