Uh, most instant read meat thermometers are not supposed to go into the oven. You pull the meat out, insert, read the temperature, return the meat (sans thermometer) to the oven.
OOPS! I did not notice that on the packaging. They are pretty worthless then, you have to pierce a hot steaming turkey with that contraption? It’s worthless. I read the packaging and didn’t notice any warnings about not placing in the oven. Thanks for the info.
