Thermocouples can come in a variety of designs suited to different applications. Unlike the base metal Type K and N wires, instead of deteriorating due to oxidation or corrosion, the platinum wires instead become soft due to long term annealing and eventually fail due to grain growth. Type S — With a pure platinum wire and a 10% rhodium platinum alloy wire, high-stability and high-accuracy type S thermocouples are also used in very high-temperature applications. Type N thermocouples can be used in applications where Type K elements have a shorter life and stability problems due to oxidation and the development of 'green rot'.
