Macy's report talks of a Delta OHM # HD37AB1347 Indoor Air
Quality Monitor, whose specifications are here

Could this invalidate the dryness measurement ?
Maybe. I don't know enough about the instrument to judge. Maybe the RH
function works even though it is out of the recommended range. I'll see
if I can ask the guy who used it.
Even if the steam is wet, the conclusion stands, but they should have
used the recommended instrument.
It looks like the HP474ARC would be a better choice.
