Abstract
The invention relates to a moisture meter tester for granular or powdered products including a cell for the product to be analyzed and a means of indirect measurement of the moisture connected to a unit for processing the measurements, the cell being adapted to be filled with and successively emptied of the product. The moisture meter of the invention is notable in that a hygrometric sensor is arranged so as to be capable of being in contact with the air surrounding the product to be analyzed, and that the sensor is connected to the measurement processing unit in order to make corrections to the values for the apparent moisture measured by the indirect measurement means. The invention also relates to a method using such a moisture tester.
