Abstrakt: We describe standard resistance thermometers made of a rhodium- iron alloy designed for operation in the temperature range 0.02-2 K. The sensitive element of the thermometer is filled with liquid helium-4 or helium3, which improves the heat exchange by several orders of magnitude. This makes it possible to significantly increase the measuring current and to use conventional technology for precise measurement of resistance. [ABSTRACT FROM AUTHOR]
