Abstract: A rheometer has an upper measuring part and a lower measuring part, between which a measuring chamber is formed for receiving a sample of a substance to be examined, wherein the two measuring parts can be moved relative to each other and, in particular, can be rotated or pivoted. Moreover, a heating device is provided for heating at least the lower measuring part and therefore the sample. The lower measuring part comprises a support part carrying the sample which can be heated through application of an electrical voltage. The support part is preferably made from glass which is itself electrically conducting and/or which can be provided with an electrically conducting medium.

Abstract: A rheometer, in particular, a rotational or extensional rheometer, comprises a lower measuring part and an upper measuring part, between which a sample space is formed for receiving a material sample, and which can be moved relative to each other. The sample space is surrounded at a distance by a cover which forms an inner closed measuring chamber, wherein a temperature sensor for detecting the temperature within the measuring chamber and a temperature control device for the measuring chamber are provided. A further sensor device serves to detect the air moisture and/or the pressure within the measuring chamber, wherein a gas and/or liquid can be supplied to the measuring chamber and can be discharged therefrom via a discharge line.
