Hey, I have the same one too, and it works pretty good. I talked to a man that runs a local hatchery here in GA. He built all of his incubators and hatches as little as 4 and as many as 120 at one time. I really didnt think about this until he said it, but, you will have a high temp and a low temp. Water will hold the temp. longer than the air surrounding it. He told me to take my highest temperature and my lowest, add them together and divide by 2 and you will have your "constant" or "fluid" temperature (I should have known this being a fireman). It appears that my bulb in the bator is brighter than me lol. To test his theory I filled some of my sons baby food jars with water, put them in the bator for an hour or so, and then pulled them out and tested the temp of the water and they were 99-100 degrees. So even though your air temp. fluctuates some, the fluid in the jars (and that in the egg) will remain at the same temp. fluctuating 1-1.5 degree. Hope this helps some. It took me a week to figure out how to get this temperature set right. I actually leave the baby food jars filled with water in the bator as to help keep the temperature more stable. Good luck!
