Method. There are several types of thermometer including the mercury-in-glass or the alcohol-in-glass thermometer, shown in the diagram below. Laboratory thermometers are available in the following types: laboratory thermometers, pecision type. An increase in temperature causes the liquid to rise up the narrow glass stem and the reading is taken from a scale on the glass . These instruments measure temperature by measuring the change in electrical resistance across a metal wire. Mercury, he found, responded more quickly to temperature changes than the previously used water.1 In 1867 the first medical thermometer was invented.

No special means are needed to measure temperature via these thermometers. The volume of the liquid and hence the length of the liquid column changes uniformly with temperature. Alcohol in glass thermometer. It is wrong, because clinical thermometer has small temperature range (35°C to 42°C or 94°F to 108°F). … the temperature range of six’s … Reading a mercury thermometer is easy but require a bit of practice and skill. Liquid-in-glass thermometer Various liquids are used in this type of instrument, depending upon the temperature range, e.g. A thermometer is a device that measures temperature or a temperature gradient (the degree of hotness or coldness of an object). Temperature Measurement Range: -10 to +360 Degree Celsius. The protected reversing thermometer (Figure S16.13) was developed especially for oceanographic use to record temperature at depth and then remain unchanged while the instrument was brought back up through the water column to the ship.It is a mercury-in-glass thermometer, which is attached to a water-sampling bottle. Question 3. FREE Shipping by Amazon. Calibrations are performed by both comparison with a standard platinum resistance thermometer (SPRT) calibrated on the International Temperature Scale of 1990 and by a limited number of fixed-points. 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 \(78^0C\). Proper measurement … Accurate body temperature readings can make a difference in treatment decisions. Mercury is a liquid metal and as such is useful for measuring higher temperatures. Price $15.50. 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. It gives fairly accurate results within the temperature range of -200 to 600°C. Keeping in mind ever-evolving requirements of our. 52.
