It is an assembly of thermocouple in which the dissimilar metal wires are made up of platinum metal and rhodium metal respectively. It's a noble metal thermocouple that provides resistance from corrosion and oxidation in high-temperature conditions. Three preparations of this thermocouple are made that differ on the base of concentration of the metals. This includes type S, type R and type B PR thermocouples. All these types offer high stability and greater precision in temperature measurements. Platinum-rhodium thermocouple assembly can be used in vacuum conditions for a short time. They are widely used in refining, cosmetic and oil, and gas industries for temperature measurements.
