Accurate Backup Thermometer?!

[Cee]

I just bought a 4 pack of thermometers online as I’ve suspicions my incubator thermometer is inaccurate and I read here it’s good to have a back up. When I opened the package today all 4 of them had different temps. Gah!
I need a good reliable thermometer. Anybody have recommendations?
Please and thank you.

You need to calibrate your thermometers to see how accurate they are. A quick search online and you will find multiple ways to do so. Any of the methods will work so pick whichever works for the types you bought. If the thermometers end up being inaccurate and there is no way to manually adjust them, they are still usable. You just need to know how many degrees off they are and add or subtract the numbers to get an accurate reading.
