Accuracy Range for Celsius Scaled Devices: Food temperature measuring devices that are scaled only in Celsius or doubly scaled in Celsius and Fahrenheit must be accurate to within ±1°C over the range of intended use.
Accuracy for Fahrenheit-Scaled Devices: Devices for measuring food temperature that are scaled only in Fahrenheit must be accurate to within ±2°F over the range of intended use.
Measure the internal temperature of food using a digital pocket metal dial or stem indicating a thermometer or thermocouple.
Food thermometer accuracy range
Within 2 to 4 °F.
Most available food thermometers will give an accurate reading within 2 to 4 °F. The reading will only be correct, however, if the thermometer is placed in the proper location in the food.
Temperature measuring devices:
Meat Thermometer made in USA
How you use your food thermometer to take a temperature will depend on the type of food you are measuring and how accurate you need it to be.
How to calibrate a digital thermometer?
A digital thermometer should always return accurate readings. Whether you use it for measuring body temperature, atmospheric temperature, or any other relevant use.
How to check Accuracy of Infrared Thermometer?
To test the accuracy of an infrared thermometer requires access to a stable surface of known temperature.
