Thermal imaging is a method of using infrared radiation and thermal energy to gather information about objects, in order to formulate images of them, even in low visibility environments.
Thermal cameras or thermal imagers are sophisticated devices comprised of a sensitive heat sensor with the capacity to pick up minute differences in temperature. As they gather the infrared radiation from objects in a particular environment, they can start to map out an image based on the differences and inflexions of the temperature measurements.
In general, thermal images are grayscale: with white representing heat, black representing colder regions, and various shades of grey indicating gradients of temperatures between the two.
However, newer models of thermal imaging cameras actually add colour to the images they produce, in order to help users better identify distinct objects more clearly — using colours such as orange, blue, yellow, red and purple. Since then, its uses have expanded far and wide, across different disciplines and for a variety of practical applications.
Electrical maintenance uses for thermal imaging are extensive. They can also help spot loose connections or devices that are starting to fail.
Plumbers use thermal imagers to inspect sites of possible leaks, mainly through walls and pipes. Call us at Contact us for detailed inquiries. Home Resources Thermal Imaging Camera.

The simplest thermal cameras evaluate heat sources centered within a single pair of crosshairs.
More sophisticated systems provide multiple points of comparison so users can analyze environmental conditions. Exactly what you need from your thermal imager depends on the environment you use it in. However, there are two areas that serve as key quality differentiators for thermal imaging cameras: detector resolution and thermal sensitivity. As with many other displays, the resolution describes the total number of pixels — for example, a x display is composed of 19, pixels.
Each individual pixel has thermal data associated with it, so larger displays produce clearer imagery. Thermal sensitivity is the threshold of difference the imager can detect. For example, if a device has 0. Minimum and maximum temperature ranges are also important.
