Blizzard killed many PA rh sensors

7 of my 14 PA RH sensors died around 8am on 2/23, the peak of the NE blizzard. They now are stuck at 100%. This makes the data from the EPA correction much higher than the rest of my PAs that have working RH.

Will they dry out and start working, or is the sensor dead forever? Are there any suggestions to dry them out? [heating to 130F for several hours did not fix it]
All 3 parameters are not reading: T/RH/BP.

Update: I replaced the sensor board and RH is reading ok now. Can these be purchased?

Thanks, George
