Really? I was going to add to my last post to correct me if I was wrong..but I got distracted by my basset poking me to get attention
Anyway, I sure hope they can get sent in! If you (or anyone else) knows where I could send it, please let me know! I've never had the need to get one calibrated, so I wouldnt know!

Calibrate your readings with a oral medical thermometer they are accurate to within .1 I believe which you will never get a constant in any incubator, unless you want to buy a lab forensic incubator. The *&#$ that comes with the still air I believe reads 2 degrees lower because it is designed to sit on top of the eggs. On a still air you should have a reading on top of the eggs 2 degrees higher than the recommended temp. But the LG instructions tell you to set incubator to standard temps. Which would indicate that the thermometer is set to read lower than actual. The temp you are looking for is the temp in the center between the top and bottom of the eggs. This is hard to get with a full incubator. I use a digital that I calibrated with a medical and leave an empty space to shim it from the bottom of the bator to center of eggs.

The air temp in an incubator fluctuates too much to use a digital quite like that. That is why we use water wigglers.
With the probe inside a wiggler, you are getting a stable reading very close to the inside of an egg.
Unless, of course, you use a proportional temp. controller, in which case the air temp is very stable.

There is a problem with water wiggler, water when heated converts heat to energy by expansion. This is why pressure is needed to reach high enough temps to sterilize. I found that the wiggler's temps were lower than the actual temps. And I tested this with a lab thermometer.
I use a pill bottle the approximate size of the eggs filled with sand. Sand does not expand significantly when exposed to heat or cold. And it dissipates and holds temps at a appropriate rate compared to the egg. The temp in the egg rises and lowers and does not stay constant. You want a average between. The LG still air (at least mine anyway) does not have over a few tenths of a degree fluctuation so I find it unnecessary. And have compared it to a medical thermometer and calibrated.
On my DIY bator I use the sand as there is a 1 to 2 degree variance on it between cycles. If you doubt this fill a coke bottle with lukewarm water and cap it and put it in your refrigerator. If you trust the wiggler that is fine, I don't. No offense meant.

I have a problem with taking the temp through the hole is the top of the lid. your probe is too close to the heating element, I believe..
I drilled a hole through the side of the bator at mid egg height and push my probe through that hole to check temps..
I use a digital candy thermometer.
it has a solid 6 inch long probe..
you can calibrate those "throw away" therms if you have one thermometer you can trust.

Sorry ... you got the physics wrong.
Water requires pressure to sterilize because water boils at 212F, and that is not high enough a temp. Pressure simply allows water to get hotter than 212F, is all.
The water wiggler is very similar to the egg in that it is mostly water, and the skin of the wiggler holds in in a space that is perfect for a temp. probe.
I am not sure how you determined that the wiggler temp was 2 degrees lower than the actual temperature. What actual temperature?
Where did you hear that sand holds temp. like an egg? I have no doubt that sand might give decent results, but the make up of sand is far from that of an egg, whereas water is similar. You would probably be better standing the probe in a small pot of water ...... the wiggler is simply more convenient.
The egg, in a decent incubator, actually varies very little in internal temp. The cycling of the heater is too fast for the egg temp to vary much.
Your post suggests a little confusion of the principles ... and you are analyzing too much.

LOL... this is getting long. No offense but I did the test with a lab thermometer borrowed from the hospital. I also checked it with the a oral medical thermometer. I will stick with my way of doing it. No offense.

none taken.
Please stop with the *my thermometer is bigger than your thermometer* stuff tho, it doesn't help.
I am trying to help you focus on what is important here. In the end tho, you have to do what you think is best. FWIW, I think you are misleading yourself a bit, but time will show you the way you need to go.
Good luck. With the amount of care you seem to be taking, I'm sure you'll do fine
