We use a Flir at work as well and when I talked on the phone with them regarding calibration they said it isn't necessary because their camera is not meant for accurate temperature measurement only differential measurements of instantaneous conditions.

When I compared the temp readings against a Fluke IR thermometer and a Honeywell thermostat the Flir was reading about 4-5 degrees above the actual conditions.

That said the delta T should be accurate in your calculations which is the most valuable data. Have you taken multiple captures of the same area over the course of, say, 10 seconds to see if the values are repeatable?

Sorry for nerding out on you there...
When I do actual product tests I complete 3 tests with the same conditions everytime. The data that I present to others is the best average between all tests. But that being said, there has not been any significant variance in numbers that would even exceed .5 degrees. I do not use multiple pieces of equipment though, I only use the flir camera for my testing.

When I take special request images I get the best image quality and take between 2-5 different images only in one sitting though.

So in short, I am very confident in any of the results that I have submitted. I have also been keeping track of all of the numbers in new tests that I have already submitted in previous tests to ensure accuracy.
