Method 1: Ice Water Fill a glass with ice cubes, then top off with cold water. Stir the water and let sit for 3 minutes. Stir again, then insert your thermometer into the glass, making sure not to touch the sides. The temperature should read 32°F (0°C). Record the difference and offset your thermometer as appropriate.

In this way, what liquid is usually used to calibrate a thermometer?Calibration in ice water or “freezing” the thermometer is best for thermometers used to measure low temperatures. Add crushed ice to a bowl or cup of distilled water to form a slushy mix at least 2” deep. Insert the thermometer stem into the slushy mix, for at least one minute.Also, how do I know if my thermometer is accurate? Insert the thermometer stem at least an inch deep in the ice water without letting the stem touch the glass. Wait for the thermometer to register; this usually takes a minute or less. The thermometer is accurate if it registers 32° F or 0° C. (My three thermometers are within 1 degree of accuracy at this end.) Also to know is, what is the most accurate method for calibrating bimetallic thermometers? Bimetallic stemmed thermometers are calibrated using the ice-point method. Calibrate on a regular basis and after using the thermometer with very hot or very cold foods, or after dropping or jarring it. In a clean styrofoam cup, make an ice water slush by filling the cup halfway with ice cubes and the rest with water.How can I make thermometer? Steps Mix 2 1⁄2 fl oz (74 ml) of cold water with 2 1⁄2 fl oz (74 ml) of rubbing alcohol. Add a few drops of red food coloring to the solution if you want to see it better. Put the straw in the bottle so it doesn’t touch the bottom. Wrap modeling clay around the top of the straw to seal the bottle.
