IR Thermal Imagers Comparison Guide

Comparison Summary

The most important feature these cameras all have is auto-calibrating lenses. In the past, if you wanted to add a telephoto or wide-angle lens after you received your camera, you would have to send it back to FLIR to get it calibrated. Now, with the new series of lenses, you can borrow one from a co-worker or buy on and just put it on your camera and it will work right away. You can get a 14° telephoto lens, the standard 24° lens or a 42° wide-angle lens, in a kit or at any time. Unfortunately, the old lenses are not compatible with the new cameras, nor are the new lenses able to be used on the old Exx cameras.

They all have a bright, pixel-free 4” touch-screen display. It has a 160° viewing angle, so you can see the image perfectly clear from just about anywhere. It is covered in scratch-resistant Dragontrail™ Glass. The thermal sensitivity on all three cameras is a very low 30mK and they all have a 6” minimum focus distance. They also have autofocusing (either spot or continuous) as well as manual focus. They incorporate a laser distance meter to give you the distance to your object.

How do they differ?

The FLIR E75 has a 320 x 240 pixel resolution (76,800 pixels). It has a max temperature of 1200F (650C) and a single spot measurement (on camera).

The FLIR E85 increases pixel count to 110,592 or 384 x 288. It has a max temperature of 2192F (1200C) and three spots and three area measurement. The laser distance meter can also be used to measure area in a user-defined size.

The FLIR E95 has a massive 464 x 348 pixel resolution (161,472 pixels). It has a max temperature of 2732F (1500C). It can display up to three spot measurements and three area measure. It can also calculate area, like the E85. The E95 also has time-lapse mode, so it can capture images from once every 10 seconds to once a day.
