Baragar, Arnold E. (1938) The accuracy of pressure gauges used on household steam pressure cookers (Research Bulletin: Bulletin of the Agricultural Experiment Station of Nebraska No. 99)
In the pressure cooker, high temperature is obtained by using steam under pressure. Since the pressure gauge is used as the indicator of temperature it is essential that the gauge register the correct pressure. Hence, this paper deals mainly with a study of the accuracy of both new and old pressure gauges used on steam pressure cookers. At the same time, four other phases were investigated: (1) the proper functioning of safety valves, (2) the various methods of sealing the lid to the cooker, (3) the proper evacuation of air from the cooker, and (4) the use of a thermometer as a temperature indicator.
