They are best used to check for realitive change not absolute temp, now get an IR camera looking at thousands of points we are differtn

Or, you could take shots using your IR gun at a cup full of water and ice, and shots at a pot of boiling water on the stove, and see how close they are to 32 and 212. If you can get, say, a 150 reading from a pot of boiling water (and you're not at the top of a mountain) then it's time for a new tool.
