Test Your Thermometer for Accuracy
As a first step to determine the accuracy of your device, we encourage you to perform a crushed ice bath test on your thermometer. Crushed ice is preferred as large ice cubes may have temperature discrepancies between the cubes. Performing this test is simple, quick, and can be done at home. Please review the images below for more information.
If your device is accurate, it will read within ± 0.9°F of 32°F. If it is reading accurately in this test, you can rest assured that it is reading accurately in food and at higher temperatures.
