The thermometer is accurate if it registers 32° F or 0° C. (My three thermometers are within 1 degree of accuracy at this end.) Whether you employ it for cooking, for measuring blood heat. Properly Calibrating an Infrared Thermometer. One popular method that is used to calibrate a digital meat thermometer is to fill a glass with some ice at the bottom, and then top it up with some hot or boiling water. Hold the calibration nut securely with a wrench or other tool and rotate the top of the thermometer until it reads 32˚F (0˚C). Digital thermometers can be more challenging because there are no adjustments that can be made. Most of them are made such that they use their resistive aspects to take the readings. The Ice-Water Method Find the reset button. Do digital thermometers expire? To calibrate a digital thermometer, look for the reset button. Good digital thermometers will be extremely accurate; they often feature 2-point calibration instead of 1-point calibration. Insert thermometer probe in the center of the glass of ice water, not touching the thermometer to the bottom or sides of glass. We don’t want the ice floating. Step 2: Add very cold water until the water reaches about one half inch (1 centimeter) below the top of the ice. Some digital thermometers don’t require any adjustment of a screw or nut. Check if the temperature reading on the infrared thermometer matches that of the conventional thermometer. Dip the tip of the thermometer into a cup of cold water for a few seconds. • If you want to check the accuracy of your digital thermometer and don’t need an accredited calibration certificate, this article will help: How to Test a Digital Thermometer for Accuracy • This article explains why it is so important for businesses and organizations to validate the accuracy of their thermometers with an accredited calibration certificate. Finally, thermometers require regular calibration (daily or weekly) once they are used frequently.
