In 1654 the first sealed glass tube was developed by Ferdinand II, the Grand Duke of Tuscany. Menu. Many concepts had to be explained and many theories proven for the successful invention of a thermometer. The instrument by which the temperature of bodies is registered is called a thermometer or measurer of warmth, and the method of constructing and using thermometers may be called thermometry. The history of temperature stretches back for thousands of years. Galileo Galilei is often claimed to be the inventor of … Throughout most of history, there were no thermometers to measure temperature. The thermoscope was widely used by a group of scientists in Venice that included Galileo. Galileo invented the first documented thermometer in about 1592. Thermoscopes were used from ancient times to detect changes resulting from heating and cooling. A medical thermometer (also called clinical thermometer) is used for measuring human or animal body temperature. History of laboratory thermometer . 8. Types of Thermometers. For statistically inclined minds we might just recite here that between 1641 and 1780 at least … In a mercury or alcohol thermometer the liquid expands as it is heated and contracts when it is cooled, so the length of the liquid column is longer or shorter depending on the temperature. He added four degrees of heat and four degrees of cold on either side of this neutral temperature. The first modern thermometer, made with completely closed ends and containing alcohol, was made about 20 years later by the Grand Duke of Tuscany de’Medici. They contained alcohol or mercury and were considered to be very accurate. Jan 1, 1592. Published in Quarterly Journal of Medicine, Volume 95, Issue number 4.

Early thermometers from the time of Galileo measured the expansion and contraction of … History of the Thermometer. Before the invention of the thermometer, our ancestors had no objective comeback to such snappy repartee as, “Cold enough for ya?” Temperature was subjective, measured only by the Goldilocks and the Three Bears scale: too hot, too cold, just right. Related Posts. Finally, in 1724, the Dutchman Gabriel Fahrenheit began manufacturing sealed thermometers with mercury inside of them. A thermometer is an instrument for measuring or showing temperature (how hot or cold something is). Another crucial innovation came from Christian Huygens in 1665. This can be used to provide graphical data and accurate readings that are suitable for professional use. Common types of thermometers are Medical thermometers, Infrared thermometers, Mercury thermometers, thermocouple thermometers, laboratory thermometers, Bimetallic strip thermometers… Thermometers measure temperature, by using materials that change in some way when they are heated or cooled. Hundreds of years ago scientists realized  they could measure changes in temperature by using primitive glass devices filled with liquids that expanded when they were warm and contracted when they cooled. One of the first thermoscopes was developed by Italian inventor, Galeleo Galilei in 1593.It used water as the liquid and glass bulbs inside an open tube. All rights reserved. The thermometer is a relatively recent instrument in a long history of measuring hotness and coldness. The Venetian physician Santorio Santorio is credited with being the first to put measured markings with a numerical scale on the sides of one of these air "thermoscopes," effectively creating the first thermometer. A thermometer has two important elements: a temperature sensor in which some change occurs with a change in temperature; and some means of converting this change into a numerical value.
