Beschreibung
Zusammenfassung:	The invention relates to an apparatus for the calibration of a thermometer in situ, wherein the apparatus has a temperature sensor (S) for determining a temperature (T); wherein a reference element (K) is provided for calibrating the temperature sensor (S); wherein the reference element (K) at least partially comprises a ferroelectric material (D), which experiences a phase transformation at at least one predetermined temperature (TPh) in a temperature range relevant for calibrating the temperature sensor (S).
