Type R Thermocouple (Platinum Rhodium -13% / Platinum)


#1

Type R Thermocouple (Platinum Rhodium -13% / Platinum):

The Type R is used in very high temperature applications. It has a higher percentage of Rhodium than the Type S, which makes it more expensive. The Type R is very similar to the Type S in terms of performance. It is sometimes used in lower temperature applications because of its high accuracy and stability. Type R has a slightly higher output and improved stability over the type S.

Type R Temperature Range:

Thermocouple grade wire, -58 to 2700F (-50 to 1480C)
Extension wire, 32 to 392F (0 to 200C)

Accuracy (whichever is greater):

Standard: +/- 1.5C or +/- .25%
Special Limits of Error: +/- 0.6C or 0.1%
