Each eXacal thermometer is supplied in a matching case. Optionally, a high-quality wooden carrying case can be ordered.

Manufacturer: Klasmeier / eXacal
Model: Pt/Pd Thermocouple


Platinum / Palladium thermocouples (Pt/Pd) are the most precise thermocouples manufactured in the eXacal manufactory.

  • Temperature range: 0 °C to 1500 °C
  • stress compensating design
    The design of the measuring point allows stress-free expansion of the thermocouple wires.
  • Excellent inhomogeneity
    The high purity of 99.99% and the thermal annealing of the thermowires ensure excellent inhomogeneity.
  • Small measurement uncertainty and low drift
    The achievable measurement uncertainties are better by a factor of 2 than with type R/S thermocouples.

Pt/Pd thermocouple can be used in the temperature range from 0 °C to 1500 °C with very small measurement uncertainties. As a special feature, this thermocouple uses a stress-compensating junction of the thermocouple wires. This special design ensures stress-free expansion of the platinum and palladium thermocouple wires. The different thermal expansion coefficients of the two thermocouple wires are thus compensated without mechanical stresses changing the Seebeck coefficient.
