Thermometer and humidity reading is wrong on my incubator I think

[Usrey farms]

I have a farm Innovator 4250 pro.
This is my first time hatching so I am nervous. I have seen where a lot of people have a secondary thermometer and humidity sensor to make sure there temps are right.
So I bought one and took it to my work and made sure it was calibrated. I have it in my incubator and it shows my temp is off 4-5 deg and humidity is about 10%.

So my question is do I trust the incubator or my known accurate sensor ?????

Does the temp and humidity on the incubator read differently in some way ?
Or am I way over thinking it and should adjust the incubator to match my sensor ???????
Sorry for the long post
Thanks for any info.

If I am right, the incubator you have is a more cheap and styrafoam incubator. I wouldn't be surprised if it was off on the temp and humidity reading. I would trust your thermometer.

I was wanting to make sure I wasnt missing something.

Thank you
