CALIBRATION OF INSTRUMENTS

CALIBRATION OF INSTRUMENTS

CALIBRATE WELL
- AND YOU WILL GET A TRUE READING.
IF YOU WANT TO GET ACCURATE READINGS, AND BE SURE
THE TEMPERATURE YOU SEE IS IS THE TEMPERATURE YOU GET
CALIBRATE YOUR THERMOMETER AT LEAST ONCE A YEAR.
- THE PROCEDURES OUTLINED ARE THE BEST YOU WILL EVER REQUIRE.
- AND NO MATTER WHAT YOU PAY TO A CALIBRATION LABORATORY, THEY WILL NOT BE MORE ACCURATE.
BOILING WATER IS A STANDARD REFERENCE : 100°C/212°F
THAWING ICE IS A STANDARD REFERENCE 0°C/32°F

Boiling Point Method

Bring clean tap water to a boil in a deep pan.

Put the thermometer stem or probe into the boiling water so that the sensing area is completely submerged.
Do not let the stem or probe touch the bottom or sides of the pan. Wait at least 30 seconds or until indicator stops moving.
With the thermometer stem or probe still in the water, use a wrench to turn the adjusting nut until the thermometer reads 212°F (100°C) at sea level.
If calibrating a digital thermometer, press the reset button to automatically calibrate the thermometer.

Ice Point Method

Fill a large glass with crushed ice.
Add clean tap water until the glass is full and stir well.
Put the thermometer stem or probe in the ice water mixture so that the entire sensing area is submerged.
Do not let the stem of the thermometer or probe touch the sides or bottom of the glass.
Wait at least 30 seconds or until indicator stops moving.
With the stem of the thermometer or probe still in the ice water mixture, use a wrench to turn the adjusting nut until the thermometer reads 32°F (0°C).
If calibrating a digital thermometer, press the reset button to automatically calibrate the thermometer.
