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

From time to time you might need to replace the tube and scale in the case. By following the next few steps replacement should be easy. First the old tube and scale will have to be removed. (Make sure that the instrument is cool and that you are wearing safety glasses and hand protection.) While squeezing the bottom of the case from, front to back, grasp the top of the scale with pliers and pull upward. As the bottom of the scale passes the half way point gently squeezing the top portion of the case. The tube and scale should slowly slide out of the case. (Please dispose of the old tube and scale properly.)
When replacing thermometer tube and scale gently squeeze the top portion of the case, front to back, and slowly slide the thermometer tube and scale into the case. As the bottom of the scale passes the half way point gently squeeze the case, front to back, on the bottom while continuing to slide the thermometer tube and scale into the case. At anytime feel free to call should you have any questions.

Helpful Hints:

Never Place a hot thermometer into cool water. Let the instrument return to room temperature before cleaning. Recheck your thermometer from time to time using the method described above under Receiving Your Thermometer

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 -37.97F (-38.87C).
