Application areas

in-situ-calibration of thermocouples or thermocouple measuring systems by means of temperature fixed-points (“selfcalibrating thermocouple'')
changeable insert for precision thermocouples (® type SKTE) or integrated part of industrial thermocouples
recognition and correction of emf-drifts in restricted access areas
improved measurement accuracy, reduced expenses for the preventive replacement of sensors, longer calibration periods in quality management systems
