How to calibrate
Currently, some of Escali’s mechanical thermometers can be recalibrated. There are two popular methods to calibrate a thermometer in the field. First is the ice bath method and the second is the boil water method. (All Escali thermometers are calibrated before leaving our factory.)

Ice Bath Method:
1. Fill a vessel with crushed or small ice cubes.
2. Add water into the vessel until the water fills all of the holes in between the ice, but the ice does not begin to float. Let the mixture sit for one minute to allow the water to cool properly. If the ice begins to float off the bottom, pour some water out and add more ice.
3. Insert the probe of the thermometer into the bath approximately 3 inches, and begin to gently stir the ice bath. Avoid touching the walls or bottom of the vessel with the probe while stirring. Stir long enough for the thermometer to equilibrate. This can take up to 30 seconds.
4. Once the thermometer equilibrates, the temperature reading should be 32°F or 0°C. If it is off, use a wrench to turn the nut located on the stem just below the dial unit. Confirm the adjustment by repeating step 3.

Boiling Water Method:
1. Fill a medium sized pot with 3-5 inches of distilled water and bring it to a full rolling boil. (To maximize the accuracy of the calibration, the atmospheric pressure must be 29.921 inches of mercury. This will ensure the water is boiling at 212°F/100°C. Using tap water in place of distilled water can also affect the accuracy of this calibration method.)
2. Insert the probe of the thermometer into the boiling water at least approximately 3 inches and let the thermometer equilibrate. This could take between 30 seconds and 2 minutes depending on the model. Oven Safe thermometers may take the longest.
3. Once the thermometer equilibrates, the temperature should read 212°F or 100°C. If it is off, use a wrench to turn the nut located on the stem just below the dial unit. Confirm the adjustment by repeating step 2.
