ABSTRACT:
A rheometer has a measuring chamber which is delimited by a measuring chamber wall in which at least one measuring component is disposed for acceptance of a sample. The measuring chamber can have a gas flowing through it whose temperature is controlled in a desired fashion by a first temperature control device. A second temperature control device is also disposed in the measuring chamber wall by means of which the wall of the measuring chamber can be temperature controlled to a desired temperature. To temperature control the sample, the gas flow in the measuring chamber can be switched off or at least highly reduced prior to measurement of the reological characteristic quantities and further temperature control of the measuring chamber is effected by means of the temperature control of the measuring chamber wall.
