The modern scientific field has its origins in the works by Florentine scientists in the 1600s including Galileo constructing devices able to measure relative change in temperature, but subject also to confounding with atmospheric pressure changes. These early devices were called thermoscopes. Visa mer Temperature measurement (also known as thermometry) describes the process of measuring a current local temperature for immediate or later evaluation. Datasets consisting of repeated standardized measurements can … Visa mer Attempts at standardized temperature measurement prior to the 17th century were crude at best. For instance in 170 AD, physician Claudius Galenus mixed equal portions of ice and Visa mer The temperature of the air near the surface of the Earth is measured at meteorological observatories and weather stations, … Visa mer • Timeline of temperature and pressure measurement technology • Conversion of scales of temperature Visa mer Many methods have been developed for measuring temperature. Most of these rely on measuring some physical property of a working material that varies with temperature.
