Temperature and Humidity Laboratory Services​

  • Calibration of contact thermometers from -196 °C to 1555 °C:

    • platinum resistance thermometers (PRTs) can be calibrated from -196 °C to 660 °C.
    • thermistors from 0 °C to 60 °C.

    • thermocouples from -80 °C to 1555 °C and

    • liquid-in-glass thermometers from -25 °C to 280 °C.

  • Calibration of infrared radiation thermometers from 0 °C to 1600 °C and blackbody radiation sources from 0 °C to 2000 °C.

  • Traceability for contact thermometry is obtained from thermometric fixed point cells from the triple point of argon (Ar) (-189.344 2 °C) to the freezing point of copper (1084.62 °C). (Pt-Rh thermocouples are calibrated at the melting point of palladium (1553.5 °C) using the wire-bridge method.

  • Development of calibration methods and transfer traceability to industry and African NMIs.
  • Dissemination of temperature scales by calibration of temperature sensors.

  • Provide a link between the African region and the rest of the world’s NMIs through comparison measurements in temperature and humidity.

  • Fixed points calibration of standard platinum resistance thermometers from Ar to Al points.

  • Calibration of other contact thermometers in the temperature range from -80 °C to 1600 °C.

  • Fixed point calibration of thermocouples in the temperature range from Sn to Pd points.

  • Calibration of surface thermometers in the temperature range from 0 °C to 450 °C.
