Not calibration, which implies adjusting to accuracy....
But glad I was able to help you test your devices.....makes for a much less stressful incubation when you know your readings are as close to correct as possible. :)
Most thermometers and hygrometers are not setup to be actually calibrated by the layman...
...but.....
you can test these devices for accuracy and makes notes to adjust your readings.
Below is how I tested my devices prior to hatching.
Tips on checking accuracy of thermometers and...
I think so...it's more about the ratio of salt to water than the total amount...just make sure you wait a good 12 hours for the air in the bag to become saturated and the device to register and stabilize.
Here's something I used on my last hatch in an LG with fan and turner to help keep humidity up.
I cut some pieces of colored plastic shim stock to fit in the bottom of the reservoirs because I couldn't see them to fill them during incubation and hatching.
Slowly and carefully wetting a paper...
Lots of variables with a hatch...but you did 'several' and 2 others did also, so...who knows?.....wonder if the change in the housing shape changed the air circulation?
You can 'test' your thermometers (and hygrometers) and note the differences to avoid the above confusion..Here's what I did :
Tips on checking accuracy of thermometers and hygrometers:
The thing you want to do is check that any of thermometers and hygrometers are correct by testing them...
You can't actually calibrate most thermometers, or hygrometers, but you can test them against a known then record the differences to apply to your readings.
Do you have a candy thermometer?
This is how I 'calibrated' my thermometers"
The thing you want to do is check that any of thermometers and hygrometers are correct by testing them against a known criteria.
Comparing devices is useless unless you know how accurate any of them are.
I used a...
I suppose it's possible, but sounds like mess to me. Even 41 eggs hatching is VERY crowded in there.
There's barely room for the hatched chicks to stand on the wire without bumping their heads on the heating element, let alone on top of a layer of eggs.
Stacking would also inhibit even heat...
I would not suggest boiling it...I just soaked mine in very warm water (120 degrees F) until all the gunk soaked off, then a 10% bleach solution rinse.
Mild bleach solution should gas off after air drying for several days.
Once you get your hygrometer, test it for accuracy.

After laboriously reading this entire thread a couple months ago, I found many tips and experiences helped...but the milk cap tip was one of the best!
From my own experience, stable room temps and patience is the key to temp control. If you make a change...wait, like an hour at least...for it to...
There were 2 spread sheets linked in this long thread......and I forgot to save one of them and now I can't find it...anyone have a copy they can post? One was called 'eggs WEEKS' but it was the other one I missed. TIA
