Calibration

High-temperature precision thermometers can be calibrated in our own DAkkS calibration laboratory. DAkkS accreditation ensures that all calibrations are traceable to national and international standards.

The high-temperature precision thermometers have been designed in such a way that they can be calibrated very well at temperature fixed points up to the aluminium fixed point. In the temperature range from 660 °C to 850 °C, calibration is also carried out using the comparison method. The measurement uncertainty is calculated from many components. The largest contributions to the measurement uncertainty balance are the reproducibility of the thermometer, ITS-90 deviation function, self-heating and hysteresis of the temperature sensor.
