Earlier in the year we got a Flir E6 Pro at work to help find overheating components inside cameras. But I wanted to see what I could capture with it outside work. I brought it home to capture my cats, my cast iron skillet on a hot grill, my wooden cup with hot tea in it, and a scene at a nearby arboretum. I have found water leaks inside walls, spots in my house ceiling where the insulation is thinnest, animals hiding in bushes, and how cool my hybrid car's disc brakes stay after a short drive. There are more affordable ones in the market, but we wanted something that was standalone (no dependency on smart devices), decent resolution (240x180 is good for the price), and robust build.
Ps. The temperature range in the images (in Fahrenheit) is shown on the right side of each image.
So here's one of the actual uses we got this camera for. This is a custom Nikon Z9 that was used by NASA for testing purposes. The camera was unresponsive, except it made clicking sounds every so often. And every time the click happened, I would see the hottest area in the image change. A 0.2F degree change, but it was sensed by the camera. We determined the board was no good, and since this is a custom Z9, it goes back to Japan (not repairable here in the USA). Custom Z9 bodies cost about 40% more than a standard one.
