Is there a way to calibrate our thermal imaging cameras ourselves

Is there a way to calibrate our thermal imaging cameras ourselves without having to send them back to the manufacturer? For example, Flir wants $800 for this service.

Greg: Well, the people that work at Flir Systems have to eat too. The bottom line is there’s one main reason for sending the camera back and getting what’s called a certificate. Now Peter had a job he was doing for the Navy and Lockheed, and they both required that certificate. If you’re doing houses, I dare say, nobody’s going to walk up to you and say “Can I have the certificate for a calibration of your camera”. Now, the second part of the question, of course, is then how do I check it, and the best way to do it is courier it to somebody that has a black body device, a calibrating device, something that can be set at an exact temperature and then you look at it and you see what the temperature actually is compared to your camera. But there’s an easier way to do it, most of the people that are on this call, I dare say, are doing things that go from maybe 25 or 30 degrees Fahrenheit to maybe a couple of hundred degrees Fahrenheit, and the way to do it is make an ice bath, get a bowl and put ice in it, fill it up with ice, and get enough water in it, and when you’re stirring it, stir it around until it starts to melt and then take a temperature and it should be around 32-33 degrees, and then do the same thing with boiling water, and note how far off they are, and that’s a pretty simple way to do it.

Dean: Right.

Greg: Now, if you’ve got to get a certificate then get one and pay them the $800.
