digital thermometer issues

[blake w]

anyone have a good method of testing a digital thermometer? i have two different ones inside the 'bator' and both are reading different temps...i also have a new one on order that reads both temp and humidity...guessing it will maybe clear things up or my luck, give me a third different reading...the two i have now usually read about two degrees different...i also have a regular glass type in there that im "trusting" but the digitals are sure nice and easy to read....thoughts?

I gave up on digital because they are notoriously inaccurate for the purposes of incubating, where you need the temp to be precise. I only use analog now. Its a little more work to have to squint to see which line the needle is lined up to, versus reading a digital printout, but I'd rather do that than wonder and worry if my digital read out is anywhere close to the real temp.
