Ozexpat and anyone else that may know!! I think we discussed this at some point.... see below paste..... Are these infrared thermometers the same as the kiddos ear thermometer things? This may in fact help when trying to go through dark or colored eggs in which its hard to see inside... ALSO wondering how much more heat difference there would be at say DAY 18 of a live vs dead embryo??? Thanks for your help... I have not investigated much with the newly departedother than ripping them open.....![]()
Checking eggshell temperature
The only tool needed to do this is an infra-red thermometer, such as the Braun ThermoScan 4520. The egg shell temperature is an accurate guide for the temperature of the embryo itself.
Remember!
Eggshell temperatures must be taken at the equator of the egg (image 1), because over the aircell the reading will register lower than the true embryo temperature. Use eggs with live embryos as an infertile egg will not be producing heat.

The measured temperatures were used to identify the upside-down and empty eggs by calculating the average temperature of all of the eggs and classifying those eggs having temperatures at least 5 degrees less than the average temperature as empty or upside-down REFER TO TABLE ONE... http://www.google.com/patents/WO2000067566A1?cl=en
