The glass Thermometer that came with the Brisnea Octagon20 bator isnt agreeing with my accurite digital themometer. I have been trying to regulate the temps for about 3days in prep to set a few eggs and cant seem to get the temps adjusted. The glass thermometer is saying 101 degrees but the bulb is located just below the blower fan in direct exposure to the heat source. I have placed the accurite wire in the same proximity as the glass and I get a reading of about 100.5 degrees so I am assuming the glass thermometer and accurite are pretty close to the same readings. The main body of the accurite is placed in the egg tray and is reading 99.5 degrees and if the wire is placed in the opposite end of the tray it reads 99.7 degrees. Question is, do I adjust the temps in the egg trays to stay in their current ranges, or do I adjust the heat at the glass thermometer to where it is in the correct range. I'm thinking I should go with the temp reading in the trays and forget about the glass thermometer reading, but I am just wanting to be sure. Anyways I set the eggs about a hour ago and left the accurite thermometer in the bator and will take temp readings when it stabilizes again in a few hours.
