0.5mm ISO9001 B/R/S Type Platinum Rhodium Thermocouple Bare Wire
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.
Consideration for bare wire type R thermocouple applications:
· Heating - Gas burners for ovens
· Cooling - Freezers
· Engine protection - Temperatures and surface temperatures
· High temperature control - Iron casting
