Understanding surface temperature differential is crucial during moisture testing. This differential refers to the temperature difference between two surfaces, such as a wall’s surface and the air near it. This difference can indicate hidden moisture issues that may not be apparent on the surface.
1. **Acquire a Thermal Camera:** A thermal camera captures the surface temperature of objects by detecting infrared radiation. It will help visualize temperature variations on the wall.
2. **Prepare the Wall:** Ensure the wall is clean and free from any objects or obstructions.
3. **Position the Camera:** Hold the thermal camera a few feet from the wall, maintaining a level surface.
4. **Scan the Wall:** Slowly move the camera across the wall, capturing images of the surface temperatures.
5. **Analyze the Results:** Identify areas on the wall that appear significantly cooler or warmer than others. These areas may indicate moisture presence.
6. **Validate the Findings:** Use a moisture meter to confirm the presence of moisture in the suspected areas.
By incorporating surface temperature differential measurement into your moisture testing routine, you can detect hidden moisture problems accurately and non-destructively, leading to timely intervention and effective solutions.
