Thermal imaging is a non-invasive technology that utilizes infrared cameras to detect and measure heat emissions from objects or surfaces. This process converts the detected heat into visible images, allowing inspectors to identify areas of concern. Its use in inspections is invaluable as it enables inspectors to spot issues that cannot be seen with the naked eye.
Common usages of thermal imaging include building inspections, electrical inspections, HVAC inspections, plumbing inspections and even machinery and equipment evaluations. Thermal imaging can also be used in mold detection by identifying areas of high moisture which may indicate mold growth underneath walls or other areas inaccessible to direct observation.
How Thermal Imaging Works
Thermal imaging cameras are specialized devices that use sensors to detect infrared radiation (heat energy) emitted from objects or surfaces. These cameras offer an accurate way of measuring temperature differences between various objects or surfaces and producing images based on the detected thermal variations. This technology works by following the principle of heat transfer, wherein thermal energy is transferred from hot objects to cooler ones via conduction, convection, or radiation.
The generated images then show areas with different degrees of temperature, enabling inspectors to identify potential issues like air leaks, moisture seepage or high electrical resistance.
Common Uses of Thermal Imaging in Inspections
Thermal imaging, or the use of infrared cameras to capture thermal images and temperatures, is a valuable tool for identifying electrical system faults, HVAC malfunctions, insulation failures, moisture intrusions, and plumbing leaks. Electrical inspections can detect hotspots and potential hazards such as overloaded circuits and damaged components. Building inspections can identify areas that require additional insulation or weather sealing to reduce utility costs.
Inspections of HVAC systems can detect leaks or blockages and improve efficiency. Plumbing inspections can identify areas that need repair or replacement to prevent water damage and mold growth.
Benefits of Thermal Imaging in Inspections
Thermal imaging provides numerous benefits when used in inspections, including non-destructive testing, early detection of potential issues, improved accuracy of inspections and more. When selecting a qualified thermal imaging inspector, it is important to consider their certification and training requirements, experience and reputation as well as the equipment and technology they utilize.
Certified Infrared Thermographers (CIT) or Infrared Training Centers (ITC) with proven track records and positive reviews from past clients utilizing up-to-date equipment are ideal.
