While mercury thermometers can measure temperature within one degree Celsius, digital thermometers can be as accurate as 0.001 degrees C a difference of four orders of magnitude in accuracy.

Nor is there any clamor from thermometer manufacturers to save the devices from oblivion. Only one U.S. manufacturer of mercury thermometers — Miller & Weber, in Queens, N.Y. — remains in ...

If you’re still using a mercury-and-glass thermometer to check a fever, read on. During the past decade, a quiet revolution has taken place, making them nearly obsolete. The new way is digital.

Spirit thermometers use a non-toxic alcohol instead of mercury to register the temperature. Like liquid mercury, the alcohol expands in volume as it gets warmer, causing the liquid to move up the ...

Digital thermometers are the most accurate way to measure body temperature. There are many types, including oral, rectal, and forehead, plus many that are multifunctional.

A primarily clinical trial has been undertaken to investigate and compare the use of mercury and digital thermometers in a ward situation. Both laboratory and clinical studies show that there is no ...

In actuality, this liquid is more often alcohol than mercury. Another advantage of alcohol is that the freezing temperature of mercury is around -38F, so a mercury thermometer is not useful in ...

Temperature is commonly measured with a mercury thermometer. The liquid mercury inside the thermometer expands and rises when heat is added, or contracts and falls when heat is removed.

Spirit thermometers use a non-toxic alcohol instead of mercury to register the temperature. Like liquid mercury, the alcohol expands in volume as it gets warmer, causing the liquid to move up the ...
