Title: World's Tallest Thermometer
Content:  The World's Tallest Thermometer is a landmark in Baker, California, US. It is a steel electric sign that commemorates the weather record of 134 F recorded in nearby Death Valley on July 10, 1913. The sign weighs 76812 lb and is held together by 125 cuyd of concrete. It stands 134 ft tall and is capable of displaying a maximum temperature of 134 F, both of which are a reference to the temperature record.
Title: World's Tallest Thermometer
Content:  It was built in 1991 by the Young Electric Sign Company of Salt Lake City, Utah for Willis Herron, a Baker businessman who spent $700,000 to build the thermometer next to his Bun Boy restaurant. Its height—134 feet—was in honor of the 134-degree record temperature set in nearby Death Valley on July 10, 1913. Soon after its construction, 70-mph winds snapped the thermometer in half, and it was rebuilt. Two years later, severe gusts made the thermometer sway so much that its light bulbs popped out. Concrete was then poured inside the steel core to reinforce the monument. Herron sold the attraction and restaurant to another local businessman, Larry Dabour, who sold it in 
Title: Bert Bolle Barometer
Content:   The Bert Bolle Barometer is a large water barometer. At over 12.5 metres tall, it is recognized as the largest barometer in the world by The International Guinness Book of Records. The instrument was created in 1985 in the Netherlands; in 2007 it was reinstalled in the new Visitor Centre of Denmark, Western Australia and was removed from there in 2011.
Title: Medical thermometer
Content:  The traditional thermometer is a glass tube with a bulb at one end containing a liquid which expands in a uniform manner with temperature. The tube itself is narrow (capillary) and has calibration markings along it. The liquid is often mercury, but alcohol thermometers use a colored alcohol. Medically, a maximum thermometer is often used, which indicates the maximum temperature reached even after it is removed from the body. To use the thermometer, the bulb is placed in the location where the temperature is to be measured and left long enough to be certain to reach thermal equilibrium—typically five minutes in the mouth and ten minutes under the armpit. Maximum-reading is achieved by means of a constriction in the neck close to the bulb. As the temperature of the bulb rises, the liquid expands up the tube through the constriction. When the temperature falls, the column of liquid breaks at the constriction and cannot return to the bulb, thus remaining stationary in the tube. After reading the value, the thermometer must be reset by repeatedly swinging it sharply to shake the liquid back through the constriction.
Title: Highest temperature recorded on Earth
Content:  The highest temperature recorded on Earth has been measured in three major ways: air, ground, and via satellite observation. The former of the three is used as the standard measurement due to persistent issues with unreliable ground and satellite readings. Air measurements are noted by the World Meteorological Organization (WMO) and Guinness World Records among others as the standard to be used for determining the official record. The current official highest registered air temperature on Earth is 56.7 °C, recorded on 10 July 1913 at Furnace Creek Ranch, in Death Valley in the United States. For ninety years, a former record that was measured in Libya had been in place, until it was decertified in 2012 based on evidence that it was an 
Title: Six's thermometer
Content:  The original Six's thermometer design contains mercury, which has been banned for most uses in the European Union and some other parts of the world. In 2006, S.Brannan & Sons Ltd, a UK company, was granted a patent for a mercury-free version of Six's maximum–minimum thermometer: instead of mercury two immiscible liquids are used supporting an index. The thermometer operates in the same way as the mercury version. Electronic thermometers often include a maximum–minimum registering feature.
Title: Highest temperature recorded on Earth
Content:   The standard measuring conditions for temperature are in the air, 1.5 m above the ground, and shielded from direct sunlight. Global surface temperatures as a whole have been monitored since the 1880s when record keeping began. According to the World Meteorological Organization (WMO), the highest registered air temperature on Earth was 56.7 °C in Furnace Creek Ranch, California, located in Death Valley in the United States, on 10 July 1913. This record was surpassed in 1922 by a reading of 57.8 °C, registered on 13 September 1922, in ‘Aziziya, Libya. Ninety years later, this record was decertified, making the former reading in Death Valley the World's highest official temperature again. The decertification of the former record in Libya has since cast doubt on the validity of the 1913 
Title: Thermometer
Content:   A thermometer is a device that measures temperature or a temperature gradient (the degree of hotness or coldness of an object). A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale that is marked on a mercury-in-glass thermometer or the digital readout on an infrared model). Thermometers are widely used in technology and industry to monitor processes, in meteorology, in medicine, and in scientific research. Some of the principles of the thermometer were known to Greek philosophers of two thousand years 
Title: Mercury-in-glass thermometer
Content:  A maximum minimum thermometer, also known as Six's thermometer, is a thermometer which registers the maximum and minimum temperatures reached over a period of time, typically 24 hours. The original design contains mercury, but solely as a way to indicate the position of a column of alcohol whose expansion indicates the temperature; it is not a thermometer operated by the expansion of mercury; mercury-free versions are available.
Title: Tall-stem thermometers
Content:   The tall-stem thermometers are a kind of thermometer, resting on branched feet. The stems carry enamel buttons indicating the degrees of one of the thermometric scales used by the Accademia del Cimento in Florence. The black buttons indicate single degrees, the white buttons ten degrees, and the blue buttons one hundred degrees. The thermometric liquid is acquarzente.
