The FLIR Ex Series

The FLIR Ex Thermal Cameras

FLIR has an ever growing range of thermal cameras that meet any need you could think of. From tiny little thermal sensors that fit onto your iPhone, to large scale surveillance units, they’re used by scientists, military, law-enforcement, educational institutions and trades-people. If you’re the latter, there’s a particular series that’s perfect for you. Say hello to the Ex Series Thermal Cameras…




What’s under the Hood?

There are a total of four cameras in the Ex series. The E4, E5, E6 and E8.

Physically all the Ex series cameras look identical except for the model name displayed directly above the 3″ LCD screen, but internally they’re very different. Let’s take a closer look…

Which camera is best for me?

As you can see from the information above, the four thermal cameras in the Ex range do share some common functionality, but they also differ in many ways. This can be a little confusing when choosing a camera from the Ex series.

The first thing you must take into account is your budget as there is quiet a price difference between the four camera models. Ranging from approximately AUD $1400 to $5500 it is important to make the right choice.

The second point that must be addressed is your purpose. What are you going to be using the camera for? Are you going to require a sharp image or will a low detailed image give you the information you need? This is where you have to consider the camera’s “Thermal Sensor”. As the images above show, the higher the thermal sensor’s resolution, the higher the accuracy of the image.

The E4

This is the baby of the series and is a good camera suitable for a wide range of situations. If you require basic temperature gauging and inspection then it will achieve that with no issues. But don’t expect the sort of detail, or clarity you may get with the higher models.

The E5 & E6

For most trades related projects (plumbing, electrical, building structure, moisture investigations, energy efficiency, etc) an E5 or E6 are perfect as their features and thermal sensor resolution along with their price tag make them good value for money. The E5 functions are closer to the E4 while the E6 is closer to the E8.

The E8

This camera is the most advanced, equipped with the highest resolution thermal sensor with the most accurate thermal range. The E8 is ideal for all the above stated trades as well as the veterinary, medical and mechanical fields, however naturally this all comes with a much higher price.

At the end of the day your budget may dictate your choice of camera, but have in mind that buying the wrong camera for the job may end up costing you more in the long term.
