Web1 day ago · Over the three-year period for which records have been made available, probes returned temperatures higher than the mercury thermometers placed alongside them 41 per cent of the time. WebDec 14, 2011 · Mercury thermometers have typically been employed for measurements in the range of -38 o C to 400 o C. Similar liquid-in-glass designs employing an organic fluid can have a range of -196 o C to 150 o C, depending on the fluid properties. "Out of the box" accuracy for such devices is generally about one scale division.
WebMercury. Mercury is used primarily for the manufacture of industrial chemicals or for electrical and electronic applications. However, because of its toxicity, many uses of mercury are being phased out or are under review. It is used in some thermometers, especially ones which are used to measure high temperatures.
WebTemperature. Most metals are good conductors of heat and they are solids at room temperature. Mercury is a good conductor of heat. It is used in thermometers because it has a high coefficient of expansion. Its stage indicates the temperature as rapidly as potential and perfectly.
