FLIR i7 vs i5 vs i3 – Which is Best for You?

FLIR i7 vs i5 vs i3

Forward-Looking Infrared (FLIR) is one of the most popular thermal imaging manufacturers, FLIR uses thermal imaging technology which senses infrared radiation, the thermal sensor is installed in FLIR and it helps the pilots and drivers for steering the vehicle at night and detect warm objects on color background. FLIR i series introduced three models FLIR i3, FLIR i5 and FLIR i7, these models are affordable, easy to operate, and light.

FLIR thermal camera detects infrared energy, and it can convert into an electronic signal. An infrared camera or thermal imager is a non-contact device that senses heat and it can be specifically quantified which identifies heat-related problems also. The recent innovation of infrared camera has the most cost-effective thermal analysis solution, software development features, automatic functionality, and detection technology.

 About Thermal Imaging Camera

Thermal imaging cameras allow us to see an object’s heat and record the temperature, it assigns the shade of color for each temperature.

The colder temperature gives a shade of blue, purple, and green, the warmer temperature can be assigned the shade of colors like red, orange, and yellow.

In the right side image, you can see the person is showed in shades of red, orange, and yellow, while other areas are blue and purple which is because those persons are radiating more heat than surrounding objects.
