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. 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. With the parameters from the calibration certificate, the high-temperature precision thermometer can be used with the respective deviation function in the temperature range from -38 °C to 660 °C.
