How do you measure timber moisture content?

The two primary methods are: (1) Pin-type resistance meters — two pins are driven into the timber and electrical resistance between them indicates MC (quick, non-destructive, ±1% accuracy). (2) Oven-dry method — a sample is weighed, dried at 103°C until constant weight, then MC is calculated from the weight difference (definitive reference method, destructive).
