Platinum/palladium (Pt/Pd) thermocouples have been developed to:

  • Accurately and reliably operate at high temperatures (up to 1500 °C)
  • Offer superior stability to conventional Pt-Rh thermocouples
  • Offer superior thermoelectric homogeneity to conventional Pt-Rh thermocouples

They now can be purchased from NPL, UKAS calibrated with an uncertainty of ± 0.2 °C, from 0 °C to 1100 °C rising linearly to ± 0.7 °C at 1500 °C.
