Hi, I'm new to the using an incubator. I purchased a 1202 GQF Bator, It's and older cabinet model with 3 turners and a hatch tray in the bottom. I have had a hard time keeping the temp steady, so I called GQF to see if I needed to replace any parts. One of the first questions he asked is where i had the thermometer placed and I told him at egg level. I was told that the thermometer was to be placed at the top in the hole where it reads the temp coming out of the heater. Well, I thought that the eggs are to be at 99.5. If I set the therm at the top where the heat comes out at 99.5 the temp at the top of the eggs is 97.2. Can someone please clarify this for me? I am using two digital thermometers if that makes any difference. Thanks in advance for your reply.
