ABSTRACT:
A measuring instrument for gravimetric moisture determination of a sample has a radiator, a weighing cell, and a sample receiver which can be connected to the weighing cell. The sample receiver allows the sample to be placed on or removed from the sample receiver. The radiator is positioned either above or below the sample, or both above and below, relative to the load direction of the weighing cell. A rotatably mounted heat conductor whose axis of rotation is orthogonal to the plane in which the sample or the sample receiver extends is positioned between the radiator and the sample. The heat conductor absorbs at least part of the radiation that impinges upon it and releases the absorbed radiation to the sample through at least one radiation-releasing surface. Through its ability to rotate, the heat conductor irradiates the entire sample surface.
