Frequently Asked Questions

Can you leave an instant read thermometer in the meat while cooking?
No — most instant read thermometers are not designed to remain in meat during cooking and will be damaged by sustained oven or grill heat. Only use leave-in probe thermometers (with heat-resistant cables or wireless probes) for monitoring during the cook.
What is a leave-in probe thermometer?
A leave-in probe is inserted into the meat before it goes into the oven or smoker and remains there throughout cooking. The probe connects to a base unit or transmits wirelessly so you can monitor the temperature without opening the lid. These are essential for long cooks (brisket, turkey, pork shoulder).
Which type of thermometer is more accurate?
Both can be highly accurate (±1°F or better). Accuracy depends more on calibration and quality than on thermometer type. Instant reads tend to be checked and recalibrated more easily (ice water test). Both should be verified periodically — see our Thermometer Calibration Tester tool.
