Moisture mapping refers to the process of creating visual representations of moisture levels within a structure or an area. These maps aid in identifying and understanding moisture distribution, which is essential for diagnosing and resolving moisture issues effectively.
Various methods are employed for moisture mapping, each with unique advantages and applications:
Depending on the detection method employed, moisture mapping involves:
Infrared Thermography: A thermal camera captures images of surface temperatures, highlighting areas with higher moisture levels that appear cooler.
Electrical Impedance Tomography: Electrodes are attached to the material's surface, and when an electric current is passed through it, the impedance variations provide information about moisture distribution.
Microwaves: Microwaves are emitted into the material, and the strength and phase of the reflected signals indicate moisture content.
Nuclear Magnetic Resonance: Hydrogen atoms in water molecules are magnetized and emit signals, which are used to create detailed moisture maps.
