@kelseyk I have these, multiple per incubator: https://www.amazon.com/dp/B07DWMJKP5?ref=ppx_pop_mob_ap_share
I like them because they store the temp history so you can see the fluctuations in temp and they can be calibrated.
I actually have a smaller Govee thermometer/hydrometer in all 3 of my hovabators for that same reason! It would be the white square thing sitting in the egg cup behind the large dial thermometer with the number 2 written on it. I love being able to track the temp. I have found that they will go haywire for short periods of time every now and then (like read 3-5 degrees cooler or warmer for a day or so then go back to normal).
