Noteworthy Features

The Ex Series models aren’t very flashy, but what they do, they do well.

It’s worth noting that these are shared features of the Ex Series, and any model that has different features will be noted.

The main differences with the Ex Series is that the resolution and screen options increase with each model.

FLIR Ex Series E5

Light Weight

Each Ex Series thermal imager is the same size, and all of them weigh 1.27 lbs, making them comfortable to use and carry for long periods of time.

These are built for extended usage, so the light amount of weight can save you a great deal of discomfort if you are in a situation where you will be using them for hours.

Large Screen

Each Ex Series thermal imager includes a 3.0 inch, 320 x 240 LCD screen, with a frame rate of 9 Hz.

They are all offer IR imaging, along with a regular visual image, a browsable thumbnail gallery, and MSX visual image detailing. The E8 offers picture-in-picture viewing options, which can come in very handy.

Large Field of View, Easy File Access

The Ex Series imagers all possess a 45° x 34° field of view, and are capable of showing the image in iron, grey, and rainbow color palettes.

Up to 500 images are stored as JPEGS that are easily transferred to a computer via USB where they can be further enhances and analyzed with FLIR Tools software.

FLIR Ex Series

Extra Durable

Like most FLIR handheld thermal imagers, the Ex series imagers can all survive drops from up to 6.6 feet. You aren’t likely to drop one from that height but if so, you’re fine.

Ease of Use

FLIR gives a nod to Apple with the Ex Series interface. Most of the controls can settings can be operated by a single button located in the middle under the screen. The button is big enough to use even if you are wearing gloves.


FLIR Ex thermal cameras are great tool for mechanical, HVAC and electrical inspections, but they aren't the most feature-rich.

FLIR Ex Series

No Lasers

FLIR has no qualms with putting laser pointers on some of their more inexpensive models, so it seems strange that they left them off to the Ex Series. 

Temperature Range

The Ex Series temperature range of -4°F to 482°F is not adequate for higher-end industrial applications. If you need to take images of high heat environments, then you need to look elsewhere.


  • Resolution: 80 x 60 to 320 x 240
  • Temperature Range: -4°F to 482°F
  • Weight: 1.27 lbs.
  • Sensitivity: <0.15°C - 0.06°C
