Does altitude affect the accuracy of an incubator thermometer?

[peepblessed]

We are building a homemade incubator and have about 6 thermometers in it as we try to test the temperature. All six have different readings!!

The two simple ones purchased at TSC specifically for incubating are 6 degrees apart when sitting side be side.

I'm now having a thermometer meltdown!! We live at 3000 ft. Anyone else have a solve this issue?

I would think if altitude was a factor, all of the thermometers would be consistant one with another.

I know that atmospheric pressure is affected by altitude.

Here's a link about atmospheric pressure and how temperature is affected. I think it also talks about calibrating thermometers too.

Actually, I didn't think the altitude made them different. I just wondered if it is something to be concerned about once I get them right. Thanks for the site. I'll check it out!!
