Well trying another 75. Did the damp rag test for about 2.5 hours it finally hit 98% went another hour and didn't go beyond. 3.5 hours total..
So I heated some water in big pot and gave sensor some hot steam humidity just a few minutes around 138° and saw 97% once. Took out cooled down to room temperature, 40% humidity.
Did the wet rag test again and it quickly reached 98% this time followed by 99% within 10 minutes total time where its still holding now for 15 minutes.
So my question do these sensors need broke-in?
As I was getting ready to post just noticed 100%....Hee haw
