Moisture meters:

Moisture meters are instruments used to measure the moisture content in wood, construction materials, and other solid materials. Available in pin-type and pinless (non-invasive) models, these devices determine moisture levels by measuring either the electrical resistance or dielectric properties of the material. Results are typically displayed as a percentage moisture content. Modern digital moisture meters often include pre-programmed settings for different wood species and materials such as fiberboard, drywall, and concrete, ensuring accurate readings across various applications. Moisture meters are widely used in construction, woodworking, flooring installation, building inspection, and material quality control to help ensure materials reach equilibrium moisture content (EMC) and prevent issues such as warping, cracking, or structural damage.
