摘要： The invention relates to a device and a method for determining material moisture by thermogravimetry, said device comprising: a test chamber defined at the top by a chamber cover; a microwave field that can be generated by a magnetron and supplied to a test chamber by means of a waveguide; a tuning rod arranged in the test chamber; a sample carrier which is operatively connected to a weighing module mounted upstream of the test chamber; and at least one sensor arranged in the test chamber. The tuning rod is arranged centrally on the chamber cover, above the sample carrier, and at least one sensor is arranged on the free end of the tuning rod, opposing the chamber cover.
