Medical thermometer measurable scale on the thermoscope and wrote of it in 1625, though he possibly invented one as early as 1612. His models were bulky, impractical and took a fair amount of time to take an accurate oral reading of the patient's temperature. Two individuals switched from water to alcohol in the thermometer. Fahrenheit also created the temperature scale which is named after him, having recorded the system in 1724. The scale is still only mainly used for everyday applications in the United States, its territories and associated states (all served by the U.S. National Weather Service) as well as the
Reversing thermometer They are usually read to 0.01°C, and after the proper corrections have been applied, their readings are considered reliable to 0.02°C. Reversing thermometer Unlike most conventional mercury thermometers, a reversing thermometer is able to record a given temperature to be viewed at a later time. If the thermometer is flipped upside down, the current temperature will be shown until it is turned upright again. This was the primary device used by oceanographers to determine water temperatures below the surface of the ocean from around 1900 to 1970. It consists of a conventional bulb connected to a capillary in which a
