So, I've recently noticed that my new Brinsea Advance's temperature reading is off about 0.8-1.5 degrees from the actual temperature (it is too high). I was incubating at 99.5 and it was about 98.2 with a digital thermometer. I went ahead and bought a Brinsea spot check, which is indeed a very good thermometer, but now I've noticed that even a few inches of height difference of the probe (I insert it through the vent hole and hang it at about egg level) makes a pretty big temperature difference. For instance, at the bottom it'll read 99 or less (98.7 even), but two or three inches higher it'll read 99.6. I haven't noticed this much temperature variation in even my Hovabator, which reads about the same within a good five inches. So, I feel very unsafe with these temperatures right now and have no idea what to do. I wanted to recalibrate the Brinsea's temperature reading, as you can do, so that I could set it and trust that it would be at the right temperature, but I have NO IDEA what the temperature is when there are quite large differences in temperature only inches apart. What am I supposed to do?
