Measuring device having an electrothermal transducer for adjusting a thermal resistance, and method of operating the same

A measuring device for thermal analysis of a sample, the measuring device comprising:

• a sample receptacle for receiving the sample;
• a heating device for increasing the temperature of the sample receptacle;
• a cooling device for reducing the temperature of the sample receptacle;
• a heat transport element having a thermal resistance and being arranged between the heating device and the cooling device such that a heat flow between the heating device and the cooling device is enabled via the heat transport element;
• and
• an electrothermal transducer arranged between the heat transport element and the cooling device such that operating the electrothermal transducer adjusts the heat flow through the heat transport element;
• wherein the sample receptacle comprises two sample containers;
• and
• wherein the measuring device is configured to perform a differential measurement with respect to the two sample containers;
• and
• wherein the electrothermal transducer comprises a Peltier element.
