Best Thermal Imagers

A thermal camera or imager is a thermographic camera that captures and creates the image of an object by using infrared radiation. Since all objects and bodies exhibit heat, these thermal scanners detect the heat and can make pictures of that heat; this heat cannot be viewed by a human eye or an ordinary camera.

These thermal devices allow you to explore things in a whole new way. There’s a huge unseen world of heat radiation.

The wavelength of infrared energy has a wavelength between 1mm to 700 nanometers. Only shorter wavelengths than this can visible by the naked eye. Between 2019 and 2020, the thermal imaging and camera market grew from 4.3 billion to 7.3 billion due to Covid, as these devices help detect human body temperature without making any contact.

Thermal Market Stats

Some industrial thermal imagers like fluke ii900 sonic industrial imager are used for detecting leakage problems and electrical panels.

What Is A Thermal Imager Used For?

These cameras are used when there are things that the human eye cannot see, like leakage of gas from some source, see people around in smoke; other than that; they are also used in the military for different purposes.

Best Thermal Cameras:

Below are some of the best thermal cameras:

1) FLIR C3 Compact Thermal Imaging Inspection Camera:

Flir is one of the most famous thermal imager-making companies. This portable and slim camera allow you to carry it anywhere. You can quickly find out cold air leaks, missing insulation, and loose electrical connections through its advanced features.

Through this camera, you don’t have to worry about sharing a problem or confirming a repair from your boss or customer since this camera allows you to transfer images by connecting it to a smartphone instantly. There is no need to go back and share the report; build the report and share instantly from the workplace.

The camera also comes with a hot spot and cold spot feature so that you can quickly measure them within a defined area box; it also has a touch screen with easy orientation so that you can view it easily.

4) Fluke ii900 Sonic Industrial Imager:

This fluke ii900 sonic industrial imager is one of the best thermal imagers, especially for industrial use. It is mainly used in large plants to detect leakage as it combines ultrasound and the visual spectrum that allows the user to see compressed gas leaks.

This thermal imager fluke features a 7 inches LCD touch screen and is equipped with a bunch of microphones. This thermal imager is specially designed for noisy conditions and allows to detect air leaks even during peak operation hours.

The camera features acoustic imaging along with a blended sound map, and its frequency range is from 2kHZ to 52kHz. As a result, this fluke thermal imager doesn’t require too much training and can be used easily.

The price of this thermal imager is too high, but many industries prefer to buy it because of its advanced features and ability to detect leakages during peak operations hours.
