Keith, I had a WM2 humidity sensor which did the same under the same
circumstances (and same time of year for that matter). The reading was
100% just occasionally coming down to 95% for a short time before back
to 100%. John Dann told me to send it to McMurdo (Davis agents) who said
they would repair it for free 'if they still had a spare part in the
shed'. Part found, repaired and back to me next day. However that was
8-10 years ago. You might just find a WM2 unit being sold on ebay but
nothing at present.


George, from what I can gather it is unlikely I will be able to get a
replacement part.

It seems to be comparable to other local site on WOW this morning, with
some locations higher and others lower for humidity/dew point. I was
expecting a minus dew point today, but no one else has one around here
either, so perhaps it has dried out a bit now?

Still thinking about updating this year all the same.
