  • ​Furnaces for maintenance of uniform temperature zones from room temperature to 2300 °C
  • Traceable thermocouple calibration facility from 0 °C to 2300 °C with world-leading uncertainties
  • Calibration uncertainties range from about 0.2 °C up to 1100 °C, rising to about 0.72 °C at 1500 °C; for high temperatures these are evaluated on a case-by-case basis
  • Thermoelectric homogeneity (Seebeck coefficient) measurement apparatus based on heat pipe to 1000 °C
  • Thermocouple manufacturing facility; mainly Type R, S, B, Pt/Pd
  • High temperature gas-tight graphite furnace with gas handling and vacuum capability; maximum temperature 2300 °C
  • Materials compatibility testing facility to 2300 °C in most atmospheres and vacuum.
  • Design and construction of self-validating thermocouples
  • All measurement services accredited to ISO 17025​​
