Instant-read vs leave-in food thermometers
An instant-read model is for spot checks; an oven-safe leave-in probe can monitor a roast during cooking if its maker allows it.

What to do
- Use instant-read to test more than one point, especially pieces of different sizes or a whole bird.
- Use a leave-in probe in a thick section before cooking, keeping its sensor off bone; verify other required points at the end.
- Check the manual for sensor depth, cable routing, ambient heat limits, and cleaning.
Conditions and limits
- An instant-read body is not automatically oven-safe.
- Neither continuous display nor a timer replaces a properly placed final 165°F poultry reading.
