I was using a friends meat thermometer and I left the probe in the pork. Went back to check the temp , went to go pull the probe out of the meat and the darn end on the probe as melted. The thermo still works but I'm not getting a reading from the probe. Questions I have is the end connection that goes in the thermo, are they all the same size? I can't tell what kind of thermo this is - of course that would be to easy.
