Timeline of temperature and pressure measurement technology

Timeline

1500s

• 1592–1593 — Galileo Galilei builds a device showing variation of hotness known as the thermoscope using the contraction of air to draw water up a tube.

  1600s

• 1612 — Santorio Sanctorius makes the first thermometer for medical use
• 1617 — Giuseppe Biancani published the first clear diagram of a thermoscope
• 1624 — The word thermometer first appeared in La Récréation Mathématique by Jean Leurechon, who describes one with a scale of 8 degrees.
• 1629 — Joseph Solomon Delmedigo describes in a book an accurate sealed-glass thermometer that uses brandy
• 1638 — Robert Fludd the first thermoscope showing a scale and thus constituting a thermometer.
• 1643 — Evangelista Torricelli invents the mercury barometer
• 1654 — Ferdinando II de' Medici, Grand Duke of Tuscany, made sealed tubes part filled with alcohol, with a bulb and stem, the first modern-style thermometer, depending on the expansion of a liquid, and independent of air pressure
• 1695 — Guillaume Amontons improved the thermometer

  1700s

• 1701 — Newton publishes a method of determining the rate of heat loss of a body and introduces a scale, which had 0 degrees represent the freezing point of water, and 12 degrees for human body temperature.
• 1701 — Ole Christensen Rømer made one of the first practical thermometers. As a temperature indicator it used red wine., The temperature scale used for his thermometer had 0 representing the temperature of a salt and ice mixture.
• 1709 — Daniel Gabriel Fahrenheit constructed alcohol thermometers which were reproducible
• 1714 — Daniel Gabriel Fahrenheit invents the mercury-in-glass thermometer giving much greater precision. Using Rømer's zero point and an upper point of blood temperature, he adjusted the scale so the melting point of ice was 32 and the upper point 96, meaning that the difference of 64 could be got by dividing the intervals into 2 repeatedly.
• 1731 — René Antoine Ferchault de Réaumur produced a scale in which 0 represented the freezing point of water and 80 represented the boiling point. This was chosen as his alcohol mixture expanded 80 parts per thousand. He did not consider pressure.
• 1738 — Daniel Bernoulli asserted in Hydrodynamica the principle that as the speed of a moving fluid increases, the pressure within the fluid decreases.
• 1742 — Anders Celsius proposed a temperature scale in which 100 represented the temperature of melting ice and 0 represented the boiling point of water at a particular pressure.
• 1743 — Jean-Pierre Christin had worked independently of Celsius and developed a scale where zero represented the melting point of ice and 100 represented the boiling point but did not specify a pressure.
• 1744 — Carl Linnaeus suggested reversing the temperature scale of Anders Celsius so that 0 represented the freezing point of water and 100 represented the boiling point.
• 1782 — James Six invents the Maximum minimum thermometer

  1800s

• 1821 — Thomas Johann Seebeck invents the thermocouple
• 1844 — Lucien Vidi invents the aneroid Barograph
• 1845 — Francis Ronalds invents the first successful Barograph based on photography
• 1848 — Lord Kelvin – Kelvin scale, in his paper, On an Absolute Thermometric Scale
• 1849 — Eugène Bourdon – Bourdon_gauge
• 1849 — Henri Victor Regnault – Hypsometer
• 1864 — Henri Becquerel suggests an optical pyrometer
• 1866 — Thomas Clifford Allbutt invented a clinical thermometer that produced a body temperature reading in five minutes as opposed to twenty.
• 1871 — William Siemens describes the Resistance thermometer at the Bakerian Lecture
• 1874 — Herbert McLeod invents the McLeod gauge
• 1885 — Calender-Van Duesen invented the platinum resistance temperature device
• 1887 — Richard Assmann invents the psychrometer
• 1892 — Henri-Louis Le Châtelier builds the first optical pyrometer
• 1896 — Samuel Siegfried Karl Ritter von Basch introduced the Sphygmomanometer to measure blood pressure

  1900s

• 1906 — Marcello Pirani – Pirani gauge
• 1915 — J.C. Stevens — Chart recorder
• 1924 — Irving Langmuir — Langmuir probe
• 1930 — Samuel Ruben invented the thermistor
