For alcohol thermometers, you do not really know what liquid is in them.

Replies: There should be no problem using an alcohol thermometer horizontally.

Which is the best way to measure Temperatura with Alcohol thermometers?

The alcohol thermometer was the earliest, efficient, modern-style instrument of temperature measurement.

The liquid is often mercury, but alcohol thermometers use a colored alcohol.

The Alcohol thermometer or spirit thermometer is an alternative to the mercury-in-glass thermometer, and functions in a similar way.

But unlike mercury-in-glass thermometer, the contents of an alcohol thermometer are less toxic and will evaporate away fairly quickly.

Fahrenheit was a skilled glassblower and his alcohol thermometer was the world's first reliable thermometer.

The alcohol thermometer being used was retrieved and sent to the Bureau of Standards in Washington, D.C. to confirm the temperature.

Putting an actual alcohol thermometer in boiling water or hotter might well cause it to burst a bit dangerously, or quietly crack and bleed out its contents.

Mercury thermometers are still occasionally used in the medical field because they are more accurate than alcohol thermometers, though both are being replaced by electronic thermometers.

Other sources, including the Encyclopædia Britannica, credit German scientist Daniel Gabriel Fahrenheit with inventing the alcohol thermometer in 1709.

Temperature measurements in hyperthermia can be made using alcohol thermometer, optic fiber thermometers, infrared cameras, or differential heating measurements using traditional semiconductor-based sensing elements.

Thermometers used include glass alcohol thermometers, adhesive external plastic strip thermometers, and battery-powered LCD thermometers.

Alcohol thermometers can measure lower temperatures than mercury thermometers because mercury freezes at minus 38.8 degrees Celcius, whereas alcohol freezes at minus 115 degrees.

There is no "correct" way to use an alcohol thermometer, making stem corrections if necessary, but be aware that the range of an alcohol thermometer is 25 C and lower.

Alcohol thermometers, infrared thermometers, mercury-in-glass thermometers, recording thermometers, thermistors, and Six's thermometers are used in meteorology and climatology in various levels of the atmosphere and oceans.

Before the discovery of the true thermodynamic temperature, the thermometer defined the temperature; thermometers made with different materials would define different temperature scales (a coloured alcohol thermometer would give a slightly different reading than a mercury thermometer at, say half-scale).

If an alcohol thermometer and a mercury thermometer have same two fixed points, namely the freezing and boiling point of water, their reading will not agree with each other except at the fixed points, as the linear 1:1 relationship of expansion between any two thermometric substances may not be guaranteed.
