  • FLIR i3: Compact Thermal Imaging Camera Review

Last updated on September 17, 2022

The FLIR i3 is an entry level thermal imaging camera that has some great features however the lower resolution and lack of zoom function can be a draw back for some users; for those who need precise and very detailed images for report purposes this camera will likely fall short. For quick checks or inspections however this camera may be adequate. This unit would be more than enough (and probably too much) for a home owner or DYI’er but could be a great fit for electricians, HVAC techs and automotive mechanics who need a good quality general purpose thermal imaging camera. The temperature range is good going from -4 to 482F. This camera also has automatic focusing and a 2.8-inch display. A 2GB microSD card is also included.

This is a fully automatic camera and will take you very little time to master all functionality on it. It instantly takes thermal images that can be stored in JPEG format internally on SD card or sent over to external device via USB interface. Flir i3 is drop-proof up to 2 meters, and splash proof. 

Flir i3 price is very attractive and for someone who doesn't need a high resolution thermal sensor and wants simple operation - this is a very fine choice.
