In our glass thermometer range we have included multipacks designed for the medical profession which represent exceptional value. A thermometer has two important elements: (1) a temperature sensor (e.g. 00. Question 3. Since clinical thermometers can’t be used to measure temperature other than the human body, we need a special type of thermometers for other purposes. Unlike the mercury-in-glass thermometer, the contents of an alcohol thermometer are less toxic and will evaporate quickly. Mercury, he found, responded more quickly to temperature changes than the previously used water.1 In 1867 the first medical thermometer was invented. 795 range alcohol thermometer products below Alcohol Thermometer Thermometer Alcohol Alcohol Glass Thermometer.

Advantages and Disadvantages of Mercury Thermometers Advantages It is a good conductor of heat and hence, can measure even high temperatures. It has a wide range of temperatures. Its use above ambient temperatures is not recommended as it is not as good a conductor of heat as mercury and expands more than mercury. No special means are needed to measure temperature via these thermometers. Alcohol in glass thermometers finds major applications in measurement of low temperatures as alcohol has a freezing point of \(-114^0C\) and a boiling point of \(78^0C\). Mercury does not wet glass or cling to it, and this property, coupled with its uniform volume expansion throughout its liquid range, makes it useful in liquid-in-glass thermometers.
