For all of you that think your $40- $50 IR Temp guns are the bomb, do this little test.

Boil a pot of water in a stainless steel pot. Measure the outside of the pot right at point where the surface of the water on the inside is boiling. Guaranteed you will not see 212F like you should.

Now place a piece of BLACK electrical tape on the outside of the pot and do the same test. You will see 212F with the black tape.

How much confidence do you have in that temp gun now
