The Role Of Thermal Image Inspections

By Bernice Terry


Through thermal image inspections professionals can scan your house for any abnormality that can be found in critical points of the building. One of the common things that can be detected with the non-invasive method is moisture. Infrared technology is used for detecting thermal radiation emitted by various objects. Usually, the procedure is part of an overall home inspection.

Moisture can occur because of various reasons, like internal plumbing issues, external weather effects, leaks and condensation. The insulation and its effectiveness can also be evaluated during an inspection. Infrared images can be displayed in color, for showing the temperature of objects. The wavelength is usually between 400 and 700 nanometers.

Some objects can have a different thermal radiation in comparison to others. Three bright colors can be part of an image and these ones are red, white and yellow. The darker palette contains blue, green and purple. Normal cameras can only show surface images, while infrared equipment can show a deeper side of things. One of the advantages of the method is that is not invasive, since it does not use conveyers, motors, long wires, or large pumps.

There is no requirement for shutting down anything prior to the beginning of an operation. The technique involves a minor issue, which is the impossibility to check the subsurface damage with it. The only purpose of a device is verifying the temperature differences between multiple objects in a home. The control of the system is possible through a piece of software that is constantly updated for improving its functions. Up to 50 measurement areas exist for temperature. Real time data recording is another great feature.

There are many advantages of the method. The technology used is not expensive and the response obtained is quite fast (milliseconds). Data storage capacity is large as even moving objects can be monitored. The image resolution is very high and the majority of cameras have a wavelength of eight to twelve micrometers, which is quite long. Issues that are not visible to the naked eye can easily be seen.

There is a frequent improvement for cameras and they become more and more portable. A system can be used to store hundred of images, while audio notes can also be recorded. The angle of particular cameras could be wider, but this is a matter of choosing between different manufacturers. Laser pointers could be applied on a thermal image. Some displays are actually touchscreens and this can lead to easier data entry.

Color palettes can be modified to suits different conditions. Showing the results in various formats is possible. Even if systems have evolved in such a manner that anyone can use them, a trained specialist is usually recommended for making inspections. People should not consider the technology the same with x-ray vision, as it cannot allow them to see through walls.

Thermal image inspections are efficient techniques for detecting various problems in a home. The color variations can offer specialists important information about electrical systems, hidden water issues, or structural damage. For maintaining their houses safe and efficient, it can be crucial for people to perform regular inspections. Replacements could be made before any failure occurs for a damaged system.
