What is a moisture meter?

A moisture meter is a device that measures the moisture content of various materials, such as wood, concrete, soil, or paper. These instruments are designed to help users determine whether a material is sufficiently dry or if it requires further drying or treatment.

There are two main types of moisture meters: pin-type and pinless. Pin-type moisture meters use two or more pins that penetrate the surface of the material being tested. These pins measure the electrical resistance between them, which correlates to the moisture content of the material. Pinless moisture meters, also known as non-invasive or surface moisture meters, use electromagnetic waves to measure moisture content without physically penetrating the material.

Moisture meters are essential tools in various industries and applications, including:

  • Woodworking and lumber production
  • Construction and building restoration
  • Agriculture and soil management
  • Paper and pulp manufacturing
  • Flooring and roofing installations
