roxy do you have a human thermometer? try calibrating with one of those
You should put all of your new thermometers in a ziploc bag, squeeze the air out, seal it, and submerge the bag in a container of ice water. There should just be enough water to cover the bag without floating the ice. Leave the bag in for about 5-10 minutes, then check to see if any of them are at 32F. The one(s) that is/are are accurate. If any are off, note how much and compensate for the difference if you can't calibrate it/them. Depending on the type of thermometer, you can also do a boil test...
You didn't beat me by much, but if we compensate for size difference, I beat you by several miles! I had 5 thermometers in my IncuView... which holds a max of 27 eggs!!!Here are some pics of the thermos I use in my cabinet #1. This this the very first cabinet I built, I have since built 2 others and use them as well. This one hold 164 eggs in factory turners or 352 in rite farm holders. As you can see my temps are very consistent through out the cabinet. You've got to be able to trust your thermos and know how the read. If they are reliable, pitch them. Believe it or not, I actually have 6 thermos scattered through each cabinet. Twice a year I take 1 thermometer from each cabinet and each hatcher in to be certified. I then check the others to them.
Thanks for the tip, fire. I'll be looking into getting a couple of those when I build my future bator!
