Someone on the forum mentioned that they used one to check wheel hub temperatures when they stop. I went to Amazon and found one for under $20. It measures from -67 to + 230 F. Mine is called the MicroTemp model MT-100.
There was a second one for sale
on Amazon that was under $25 that measures to +400 F.
It's small, about 3" long and a 1/2 inch wide. Extremely easy to use.
