An infrared camera can see and measure heat differences in building materials on ceilings, walls and floors. Wet or moist areas and objects usually have a different temperature than dry areas due to evaporative cooling, increased conductance or thermal capacitance. Accordingly, the wet areas will appear relatively darker or lighter than the dry areas on an infrared picture, enabling us to locate them. An IR camera can complement a forensic moisture audit by quickly and non-destructively identifying the location and size of moisture damaged areas. These suspect areas are further evaluated with a moisture sencing meter to confirm the presence of moisture.
