Firewood should read under about 20 percent moisture before you burn it, or it hisses, smokes, and cakes your chimney with creosote. A cheap pin moisture meter tells you if a split is truly seasoned. Look for a pin-type meter with a clear wood-moisture range and a simple readout, checked on a fresh split face.
