With my first clutch coming at the end of the month (Hopefully miss Tabitha won't keep me waiting too long), I've been fine tuning my incubator. So far it holds temps beautifully and is hooked up to a herpstat 2 set at 91*. I have the probe on the heat tape which is on the bottom of the incubator and there is a fan in the center of the incubator. View the setup here: http://img196.imageshack.us/img196/6541/cdri.jpg I have 3 tubs in there (a test tub, and a tub for each clutch I'm expecting this season) and each have a different thermometer in the tubs. I recently put thermometer's in each tub and the incubator itself has at least 3 thermometers in it (I'm a bit OCD about the temps in there).
Here's my problem: all three thermometers show different temps (89.4*, 90.4*, and 91.6*) Here are the thermometers and their corresponding temps:
http://www.exo-terra.com/en/products/combometer.php this model is showing the 89.4* temp
http://zoomed.com/db/products/EntryD...D=2&SearchID=5 is showing the 90.4* temp
http://www.radioshack.com/product/in...uctId=11361231 is showing the 91.6*temp
Which thermometer should I go by? Or is there a better one out there that I should purchase? I ask because the 91.6* is a little concerning to me and I want to make sure I'm not overcooking my babies when the eggs finally arrive.
