I have a little Ofna-branded one (they're also branded under other names). It measures 20f cooler than another one I have. A buddy has the same Ofna one I have and it measures higher than both of mine. Another buddy has a different model that measures about the same as my Ofna one.

Way too many measurements that are 20f difference.

Is there a way to test the accuracy of a temp gun? Would measuring boiling water (100c/212f) give me an indication? Anyone tried this?

Boiling water does work.

Find someone with a Exergen temp gun and compare yours to that.

I did this and found that my $70 temp gun reads exactly the same as the Exergen.

I did this with my raytech and the "rayjunk" was 10 degrees cooler, not bad. But my friend has the same model raytech and his measures 40 degress hotter than mine

make sure the tip of you gun is clean this will make a big difference use a q-tip to clean it dust and oil on the tip will hurt accuracy big time

Boiling water can be used but remember that the boiling point of water depends on your altitude. At sea level it is 212, at 2000 feet it is 208, and at 5000 feet it is 203. Barometric pressure will ever so slightly affect the boiling point as well but not as much as the altitude differences.
