good question--I have wondered that myself.  I do use a digital but I compared it to my glass thermometers.  Mine is a big box, like a double deck of cards, and I'm not sure at what level the temps are taken on my mode. Doyou have a probe type?
 
My guess is that some models are beter than others-- meaning more accurate right out of the box.
 
Would love to see some other answers myself.
