Using the Calibration Tool on Sheath
- Seat the hex nut on the thermometer into the head or wrench of the sheath, depending on sheath style.
- Immerse the stem into the middle of the ice slurry or boiling water (212°F/100°C at sea level) to a depth of at least 3 inches.
- Rotate the nut clockwise to increase the reading. ...
- Stop adjusting when the pointer indicates the temperature of the water.
How to calibrate a thermometer in boiling water?
To calibrate your thermometer using the boiling point calibration method follow these steps:
- Heat a saucepan of water on the stove
- Wait for the water to come to a continuous rolling boil
- Insert the probe of the thermometer into the water
- Wait for at least three minutes and then record the reading
- To ensure the readings are correct and accurate, take readings at least two minutes apart and the results, should be within 1°C of each other. ...
What are the 3 steps for calibrating a thermometer using the ice point method?
Put the thermometer stem or probe into the ice water. Make sure the sensing area is under water. Wait 30 seconds or until the reading stays steady. Adjust the thermometer so it reads 32˚F (0˚C).

What is meant by calibration of thermometer?
A thermometer is calibrated by measurements at a series of temperature fixed points (freezing/melting points, triple points or vapour pressure points of pure materials). By using this method we insert the thermometer in a fixed point cell which provides the desired temperature point.
What is the most accurate method for calibrating bimetallic thermometers?
The most accurate method for calibrating the bimetallic thermometer is the ice-point method. To calibrate a bimetallic thermometer using this method, fill a glass completely with ice, add cold water, and let sit for 4 to 5 minutes. Then, insert the stem of the thermometer into the ice water.
Why do we need to calibrate thermometers?
Why is it necessary to calibrate a thermometer? It is necessary to calibrate a thermometer to assure accurate readings, as the accuracy of a thermometer can drift over time. Thermometers can drift over time for various reasons. One reason a thermometer can drift is mechanical shock.
How to measure temperature with a thermometer?
Fill a plastic container with crushed ice. Mix enough chilled water to produce slurry, but not enough to float the ice. Stir the slurry vigorously, insert the probe of the thermometer into the iced slurry. Wait for at least three minutes and then record the reading.
How to read a thermometer?
Heat a saucepan of water on the stove. Wait for the water to come to a continuous rolling boil. Insert the probe of the thermometer into the water. Wait for at least three minutes and then record the reading.
Why is it important to use ice point and boiling point?
If you are calibrating your thermometer yourself, it is important to use both the ice point and boiling point methods to ensure the thermometer is accurate in its upper and lower ranges.
Can you return a thermometer to the manufacturer?
Follow the manufacturer’s directions on calibrating your thermometer this way. Alternatively, you may be able to return your thermometer to the manufacturer for calibration.
Why do we calibrate thermometers?
We calibrate thermometers to ensure the displayed readings fall within the set specifications and understand the figures’ inaccuracy at specific measurement points.
What happens after you calibrate a thermometer?
After calibrating your thermometer, you will have a completely reliable tool to use in measuring temperature. You will be left assured you get an accurate temperature reading for the rest of your working session. In case of any impact on your thermometer, ensure you calibrate it before using it.
What temperature should a thermometer read?
Allow the thermometer to settle for about thirst seconds and take the reading. If you correctly do it, the thermometer should read 100°c or 212°f. In case you don’t get this, keep the thermometer submerged and make adjustments until it reads this value.
Can you calibrate a digital thermometer?
Digital thermometers are easy to calibrate since most of them have a reset button for calibration purposes. However, you will find others with a nut under the temperature dial to make adjustments. But then, you must check the manufacturer’s instructions on how to calibrate your thermometer the right way.
