The wood moisture content (MC) is vital for the wood performance and durability in external applications. Moisture pin sensors are widely used for measuring the MC of wood materials by measuring the electrical resistance of the material. They are durable and respond quickly to changes in the moisture conditions in the wood. This paper presents a laboratory study of wooden moisture pins used in an extensive field investigation on wooden cladding. In this project wooden moisture is logged by measured resistance between two steel pins, a usual method for an effective reading of the MC. The paper also describes the moisture pin function, measurements and the tests done to verify their accuracy. The laboratory study described in the paper includes both resistance and gravimetric measurements. The quality of continuous electrical resistance measurement series as well as the ability to define the current moisture profile of the cladding board by moisture pins is discussed. The laboratory measurements concluded that measuring the moisture profile was not possible for coated wood cladding.
