The FLIR i3* is a thermal imaging camera, which is very popular among thermographers.

In the following, we present the product in more detail and address weaknesses and strengths of the device.

Furthermore, we describe possible applications for which this thermal imaging camera is suitable.


FLIR i3 Wärmebildkamera

The FLIR i3 thermal imaging camera not only gives off a robust and high-quality impression to its users, it also provides good thermal images and very easy to use.

This is why it is so popular – and not least because of the good price / performance ratio – especially for the newcomers in thermography.

Technical specifications

The sensor resolution of 60 x 60 pixels and a basic accuracy of ± 2% make the device certainly not the most powerful. However, the FLIR i3 still delivers high-quality images and is well equipped for simple applications.

Alternatively, you can take advantage of the other models from the FLIR i-Series to have a higher sensor resolution at an extra charge. Please note the measuring range from -20 to 250 ° C (-4° F to 482° F) and the small 12.5 ° x 12.5 ° optics.

The picture frequency is 9 Hz on the 2.8 inch color LCD. The emission level can be set as usual from 0.1 to 1.0. Unfortunately, no digital camera is integrated for the visible spectrum.


The device can therefore not be “MSX® Thermal Image Enhancement” – where the thermal image and the visual image are superimposed.

The thermal image can be displayed in three different color palettes (iron, rainbow and black / white) in order to improve the redering of temperature differences.


The FLIR i3 is suitable for price-conscious users who want to investigate simple thermal problems. These include simple electrical circuits, small structural deficiencies at home, chimney sweep etc.

It is not recommendable for professional and daily use in building diagnostics because of the rather smaller optics and sensor resolution.

When working in particularly confined spaces, a thermal imaging camera with a larger optic should be used.

Users should choose it who want a lightweight and compact brand product in the usual quality and workmanship of FLIR.

Conclusions – FLIR i3

With the FLIR i3 beginners can do little wrong. It may not have the best IR sensor, but still delivers very good pictures – and at a very good price-performance ratio.

All in all, a device that is fun to use in thermography.
