This is a very common type of thermometer. The temperature range that it can measure falls between -37 degree Celsius (low freezing point) and 356 degree Celsius (high boiling point). There are several types of thermometer including the mercury-in-glass or the alcohol-in-glass thermometer, shown in the diagram below. It is one of the oldest thermometers available in the industry. The volume of the liquid and hence the length of the liquid column changes uniformly with temperature. Industrial Estate, Ambala 350c, Industrial Area, Phase 2, Industrial Estate, Ambala - 133006, Dist. A thermometer has two important elements: (1) a temperature sensor (e.g. R.P. 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. Mercury in its liquid form has traditionally been used because of its fluid properties of separation and adherence through temperature extremes. The ethanol version is the most widely used due to the low cost and relatively low hazard posed by the liquid in case of breakage. A typical thermometer for getting environmental temperature readings is required to have a temperature range of -20°F to 120°F i.e. The best known thermometer is the mercury-in-glass thermometer, but other liquids such as alcohol may also be used in glass thermometers. Although the accuracy of axillary temperature measurement is affected by a number of factors, device dwell time and device type are common. Price $15.50. Many are also useful for in-bottle temperature readings, special chemistry applications, and total immersion. The alcohol thermometer or spirit thermometer is an alternative to the mercury-in-glass thermometer and has similar functions. As alcohol … Thermometers are typically constructed of a hollow glass tube with a reservoir at one end to hold a liquid, which is sensitive to temperature fluctuations within a specific range. Alcohol thermometers can measure comparatively low temperatures that range from -115-78.5°C (-117 to 173.3°F), while mercury thermometers can measure relatively high temperatures ranging from −37 to 356 °C (-34.6 to 672.8°F). The temperature measurement range of alcohol thermometers varies from 115°C to 785°C, where former is the freezing temperature point of alcohol and latter is boiling temperature point of alcohol.
