Which thermometers should I trust??

[remicuties]

Currently warming up my hovabator for setting some emu eggs tomorrow I started it this morning humidity has been a stable 36-42% but temperature I’m a bit confused on.
I have seven inkbird ith-10s all reading the same humidity and temperature I got them from eBay, I have only two of them in my incubator as well as an incutherm plus the incutherm reads 100 degrees f while the inkbirds are 96.5 f, my incubator is set higher than 96 to miscount for calibration issues and I’m confused which thermometers I should be trusting right now..
The incutherm says it’s the “best” for incubating eggs but I did a ice water test and it never read 32 degrees I stuck the inkbirds in my freezer and both read 32 degrees so I’m lost.
The inkbirds allegedly came from medical people who only used them once for maybe transporting medicine etc and then the eBay seller got them and resold them so it makes me think since they’re used in medicine they must be more accurate to the incutherm right?
I also have a govee coming in the mail Monday but I don’t know if that one’s any better.

If someone can help me that’d be great.

I bought those same Inkbirds. They're fine.

I have 6 or so Govee, which unlike those Inkbirds, are calibratable. That's the advantage should their readings trend off sometime.

I've used those eBay Inkbirds extensively in 3 incubators and 2 brooders this past month and have not seen an issue yet.

So you’re saying the magical incutherm + could be the incorrect one? I salt tested some of the inkbirds they all read 75%, again in the freezer was 32 I assumed regardless if it was ice water or a freezer it would be 32 degrees but of course I’m no expert.

Really upsetting if that incutherm is wrong because it advertises as being accurate

I'm not saying anything is incorrect. You be the judge as you're the one doing the testing of them.

Go by the ones that test correctly. If the Magical incutherm can be calibrated, then calibrate it to the 7 inkbirds you have, then retest. It should then match them.

My Govees were all calibrated when the Inkbirds got here. I had a couple of Govees just sitting in a drawer and I put the Inkbirds in there, looked a bit later and everything said the same thing.

75% is correct for humidity.
Freezers can vary, so ice test them.

I am ice testing the incutherm again

I am ice testing the incutherm again

Update: it read 33 degrees f so perhaps the inkbirds are innacurate then.
I’m going to judge some more when the govee gets here

If your freezer is reading 32° then you have a problem. Freezers should be as close to 0°F (-17°C) as you can get them. I'm fairly sure a thermometer wouldn't go down to freezing and just stop unless I'm missing something here.
