I figgured you guy's/gal's would know if there are any 100% accurate thermometer to use in incubators. I bought three new ones to compare the readings and they all very two or more degrees. I have one that is twenty years old with wireless remotes that I call God to judge the others but I cant get them anymore. It was from Radio Shack. The ones they have now are from China and ....well you know. I'm about to have a heart attack from worrying about the inaccurate crap I have bought.I'd be pulling my hair out but I did that last year! The little ones that came with the hoverbator chicken incubator are working the best but you need microvishion to see them and I need wireless SOOOO what do the champs use Kelly, Kevin, Bob,Jay and the rest of you Snakegoddest with Python DNA that need 100% ACCURATE!
