ABSTRACT:
A drying balance (1) including a pan (3) that rests on a weighing system (2) as well as a heat source (5) for heating and drying a sample (4) on the pan. A sensor (11) measures the absorption coefficient, transmission coefficient, or reflection coefficient of the sample (4) in at least one predefined spectral range, or measures the moisture dependent dielectric constant of the sample while the weighing system (2) measures the moisture dependent weight of the sample (4). The drying balance allows the entire calibration curve of the sensor (11) to be determined in a single drying process.
