My camera is the seek thermal xr. It is on the low end of the thermal camera scale but it is extremely useful.
Step 1: Finding Volatile Liquid Leaks.
Using a thermal camera will easily locate even small leaks due to the significant temperature difference.
I used a can of deodorant spray to demonstrate the principal. The stream of liquid droplets from the nozzle is easily visible. Also the run of liquid deodorant on the cap is seen visually and thermally.
The same principle applies to other volatiles like gasoline, refrigerant and alcohol.
Leak detection is simplified using a thermal camera.
My preference for the images is the monochrome pallette since it provides a bit more clarity. You can of course choose to have a different color pallette.
