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
Miller-Casella thermometer the ocean was always warmer than that below. Scientists aboard the HMS Challenger later questioned this assumption and made temperature measurements with reversing thermometers instead which wouldn't require the coldest water to be at the ocean's bottom. Nature article - Miller Casella thermometer Miller-Casella thermometer The Miller-Casella thermometer was a Six's thermometer with a double bulb used extensively by the "Challenger" expedition during the late nineteenth century. The thermomemeter was used for water temperature readings along 360 different research stations around the world's oceans. The thermometer, about 9 inches in length, was enclosed in a copper case and filled with
