You may have seen my post about drying my White Oak. I have a Dr Meter MD918 that I got off of Amazon. It was giving fairly consistent numbers [that I would have expected] on the oak when I first got it starting in the high 20's down to the mid teens about a month ago. I was using the appropriate density setting and had calibrated it following the instruction book. However I wasn't real confident that it was giving accurate readings because when I would test the Pine tongue/groove boards used for the walls of the storage room, it was always reading very high [around 20%. I had reset the meter for the proper density when changing from the oak to the pine]. Room is located inside a barn and is approximately 6 years old, so I would think it was MUCH drier than 20%. Currently keeping it at 35% humidity and about 95-105 degrees with my dehumidifier and fan blowing. It does cool a little at night, but hasn't been below 90 recently.
I brought the meter in and reread the instructions to re-calibrate. Long story short the display does not do what it says it should do during the calibration process, so I don't know if it is set properly. HOWEVER
I'm now getting a reading that seems like it would be closer to normal for the pine walls. You can see the shrinkage between the boards from running the dehumidifier constantly.
AND now when I test the oak, I"m getting numbers sub 10% levels. The first 2 pics below are from 4x4's and 2x4's. The last is either a 4/4 or 3/4 board.
Thoughts? Anyone have this or a similar meter? I don't know if I should trust the new readings that I"m getting. Will Klingspor test a board for me or is there anyone in southern Wake County [Raleigh to Benson area] that might test a board if I bring it to you?
