FAQ Receiving your thermometer Upon receiving your thermometer please inspect your thermometer
for any visual damage. Sometimes in transit the mercury will become separated.
This can be easily fixed. Please consult Separation
Instructions. To check the accuracy of the thermometer place the thermometer
and about four inches of water in a pot and bring to a boil. When the
water begins to boil the thermometer should read 212° F. (This is
base on an altitude at sea level.) See Altitude
chart to adjust for different altitudes. If the thermometer does not
read 212° F please contact us before using.
This thermometer can be rechecked using this method at anytime. Replacement of Tube and Scale |

Did
you know? In making a liquid thermometer, the mercury is ordinarily driven to the top of the tube by heating. The glass is then sealed off, resulting in a vacuum when the mercury contracts during cooling. For high-temperature applications the tube is filled with a pressurized gas before sealing to prevent the mercury from boiling. Colored alcohol or other fluids are used for recording temperatures below the freezing point of mercury, which is -37.97°F (-38.87°C). |
