Product details
standard rhodium-iron resistance thermometer
The standard rhodium iron resistance thermometer is a type of resistance thermometer made by winding an alloy wire of pure rhodium and 0.5% molar iron in a stress free structure. The standard rhodium iron resistance thermometer has good resistance sensitivity in the temperature range of 0.5K to 27K, and has good long-term stability in this temperature range. Therefore, the standard rhodium iron resistance thermometer is particularly suitable for maintaining low temperature standards in the temperature range of 0.5K to 27K.
