Type R and S Thermocouple Designs

Thermocouples can come in a variety of designs suited to different applications. View the details of each type of design we offer for Type R & S.

Thermocouple Type R and Type S Technical Details

Type S and R type thermocouples are the most popular rare metal thermocouple types. They are very similar in conductor construction. The main difference is that Type R is more popular in the UK whereas Type S is more popular in Europe. As the cost of Platinum and Rhodium is high in comparison to base metal thermocouples, Type S and Type R thermocouple wire can be recovered and recycled from failed thermocouples. The negative leg on a Type R or Type S thermocouple is pure Platinum and the positive leg is Platinum/Rhodium

Type R & Type S Thermocouple Temperature Range

Continuous:

Type R: 0 to +1600°C

Type S: 0 to +1600°C
