Thermometer Accuracy?

[OhhWatALoser]

How do you measure ambient temp and humidity? The IR guns only measure surface temps.

I don't, I know my ambient temp can't be lower than the room the enclosure is in, so I'm not concerned. There are only 3 humiditys I'm concerned with, low good and high. Low looks dry, high looks soaked and eventually moldy, good lays in the middle of those 2. Doesn't matter what the gauge says to me, going to adjust based on the conditions of the enclosure anyway.
