Moisture mapping is a non-destructive testing method used to identify and locate moisture within a structure. It is a valuable tool for a variety of applications, including building diagnostics, leak detection, and energy audits.
Moisture mapping devices use a variety of sensors to detect moisture in building materials. The most common sensors are infrared cameras, which measure surface temperature, and moisture meters, which measure moisture content.
Infrared cameras can detect moisture by measuring the temperature difference between wet and dry surfaces. Wet surfaces are typically cooler than dry surfaces, so they will appear as dark spots on an infrared image.
Moisture meters measure the moisture content of a material by passing an electrical current through it. The amount of current that passes through the material is inversely proportional to its moisture content. Therefore, a high moisture content will result in a low electrical current, and vice versa.
By combining the data from infrared cameras and moisture meters, it is possible to create a detailed map of the moisture distribution within a structure.
