Made with 9 Hz image frequency, the camera has a 2.8-inch color LCD screen. You can capture the images via the screen that is reported and detailed.

For better output, you can set the emission level of the camera from 0.1 to 1.

Optimized Temperature Range

The FLIR i3 camera has a temperature range of -4 to 482F, so it is suitable for many experiments and multiple analyses.

It is equipped with 12.5°x12.5° optics, which means you get a more accurate view while analyzing major problems.

rubberized and rough protection around the camera shields it from firm work circumstances and enables you to operate as it is capable of withstanding a fall of up to 6 ‘.

Including an infrared temperature of 3,600 points, this FLIR i3 thermal camera makes sense in consolidating data with the visual field.


This device makes it easy to handle when captured the data images but has little trouble defining areas and assigning points to the final output.

It is designed for beginners, not just professionals, so it is easy to understand and operate.

The complete manual guide is provided with the camera for effortless guidance and clear operation.

For your convenience, the camera weighs just 13 ounces (ie, 365 grams), so you can operate it with just one hand.

Software & Storage

FLIR has been developed with analytics and reporting software to create automatic reports with a custom logo, which is highly compatible.

FLIR i3 comes with an integrated 2GB microSD card that can save up to 5000 images.

It instantly takes thermal images and stored it in JPEG format on the SD card. 

Other Features 

The FLIR i3 has a drop-proof up to 2 meters and comes with a splash-proof camera to get an accurate thematic image.

This i3 version is also available at the average price range so that you can get a high-resolution thermal sensor at a reasonable price.

There is also an automatic focusing option on the camera to prevent blurred images.

It comes with a rechargeable Lithium-Ion battery and a 100-240V AC adapter comes along with the package.

Furthermore, it has an built-in charging system that allows you to run this camera for more than 5 hours.
