I'll just throw out that, IMHO, non-contact thermometers are not nearly as accurate as folks think they are- you cannot simply point them at anything and see what their temperature is. I see people using them to measure air conditioner output- not good- refrigerator temps- also not good- it all depends on the material you are trying to measure. Shiny surfaces will tend to read below true temp, black surfaces tend to read correctly.

They are handy for quick measurements, and can be compensated for, but point, shoot and read the temp- not so much. If I need to know a temp, I use a thermocouple or thermistor in contact with the item.
I could care less what the "actual" temp is, what I'm looking for when using the temp gun is a significant difference. I typically will do a quick walk around, shooting tires and hubs. As long as all are similar temps, all is good. If one hub or tire is significantly hotter than the others, then I know I've got a problem.
