I had a moisture meter, but I never really used it much. If I use the driest wood available from the lot, then things are what they are and I don't try to analyze it. The first couple years I could just tell intuitively that something was up, and that moisture was most likely the issue. Not a bad issue, but something that needed more work to get around, like longer startups, or monitoring the stove more while the water boiled off, then watching it to make sure it was shut down properly and at the right time. Later, when inventory was up, I had the pick of the place to be able to use the driest available. It felt great for a change to almost be able to light a match to large splits and watch them catch easily. Over time you will be able to get a feel for it. Any moisture coming out while it burns? Does it light easily, do the splits have a ring tone vs thud, were the stacks under cover, or at least brought in during a dry time of the year, were they seasoned long enough. All questions to ask and store away to think about and learn over time.
