We manufacture type R and S thermocouples to your specifications or as replacements to existing sensors. We have manufactured thermocouples for over 15 years and are solely focused on the design and manufacture of temperature sensors. Please call or email us to discuss your requirements.
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.
Type R and S 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 R and Type S wire can be recovered and recycled from failed thermocouples.
