Meat thermometer the temperature should be at 74 °C (165 °F). For shellfish that are difficult to open, discard any that did not open during cooking. Meat thermometer A meat thermometer or cooking thermometer is a thermometer used to measure the internal temperature of meat, especially roasts and steaks, and other cooked foods. The degree of "doneness" of meat or bread correlates closely with the internal temperature, so that a thermometer reading indicates when it is cooked as desired. When cooking, food should always be cooked so that the interior reaches a temperature sufficient, that in the case of meat is enough
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 a solution of creosote in spirit. A U-shaped mercury tube recorded maximum and minimum temperature as the thermometer was lowered and raised into the ocean. This design assumed accurate measurements could be taken as long as the water closer to the surface of
