How Does the Relative Humidity Affect Moisture Testers
In some cases the drying wood could split or crack as the fibers lose moisture On the other hand if you left a piece of wood in an area with an extremely high RH it would start to absorb extra moisture from the air In the short term this could cause the wood to swell as it takes on more moisture.
