Wet-bulb temperature is the lowest temperature that can be reached by evaporative cooling of water in air. It is used to measure humidity and heat stress, and can be affected by wet-bulb events, which are extreme weather conditions that lower the wet-bulb temperature.
DSC is a thermoanalytical technique that measures the difference in heat required to increase the temperature of a sample and reference as a function of temperature. It can detect phase transitions, glass transitions, and other thermal processes in various materials and is widely used in industrial settings.
Dew point is the temperature at which air must be cooled to become saturated with water vapor. Learn how dew point depends on pressure, humidity, altitude and human comfort, and how to measure and calculate it.
Wet-bulb globe temperature (WBGT) is a measure of environmental heat that accounts for air temperature, humidity, radiant heat and air movement. It is used to determine appropriate exposure levels to high temperatures for industrial hygienists, athletes, military and others.
A calorimeter is a device for measuring the heat of chemical reactions or physical changes. Learn about the different types of calorimeters, such as adiabatic, reaction, bomb and isothermal, and their history and applications in thermodynamics, chemistry and biochemistry.
Old thermometer in a pharmacy in Vienna, showing room temperature by Reaumur scale. Réaumur and Celsius scale on thermometer. Private collection, central Europe. The Réaumur scale (French pronunciation: [ʁeomy(ː)ʁ]; °Ré, °Re, °r), also known as the "octogesimal division", [1] is a temperature scale for which the melting and boiling points of water are defined as 0 and 80 degrees ...
Learn about the history, methods and applications of measuring temperature, including thermometers, thermocouples, thermistors and more. A barometer is a device that measures atmospheric pressure, not temperature, and is not mentioned in this article.
A thermometer is a device that measures temperature or temperature gradient using a sensor and a scale. Learn about the ancient and modern developments of thermometers, from pneumatic devices to mercury-in-glass and digital models.
