i would trust the helix probe. they are rated at .9 tenths of one degree working accuracy. that is plenty for hatching eggs. for me, helix has been tested and used in enough bators to get the job done. also unless your thermometer is better than .9 in accuracy, you can't really check the helix accuracy.


can you post a pic of the bator? just curious.

being a hvac geek, i've tested out 5-6 different thermometers with helix and all have been less than 2 deg. off. most were within one degree. helix does a good job at keeping accurate and stable temps!
