How Accurate are Meat Thermometers?

Most meat thermometers are accurate to within plus or minus 1-2° F.

Tip: "Pop-up" thermometers are reliable to within 1-2°F if accurately placed in the product. The "pop-up" temperature device indicates that the food has reached the final temperature for safety and doneness. It is also suggested that the temperature be checked with a conventional thermometer in several places.

The accuracy of the meat thermometer can be verified and the thermometer "calibrated" if necessary. Some thermometers have "test" marks on them at 212°F, the boiling point of water at sea level. To test the thermometer, insert at least 2 inches of the stem into boiling water. It should read 212° F. Some thermometers, especially the "instant-read" types, have a recalibration or adjustment nut under the dial. Turn the nut if necessary to adjust.

NOTE: Water boils at a lower temperature at higher altitudes, for example 202°F at 5,000 feet.
