Abstract

A device for dosing a number of constituents according to a given formula with a scale (1) containing a formula memory. The scale (1) is equipped with a transponder read unit (2), the given formula is storable in a transponder (4) and transmittable to the formula memory with the transponder read unit (2) and the transponder read unit (2) additionally monitors the dosed constituents during the dosing process. The storage containers (6) for the individual constituents are each provided with transponders (7), so that the individual constituents can be identified by the transponder read unit (2). This enables a simple and reliable transmission of the formula data to the formula memory of the scale and monitoring of the dosing process. Furthermore, the scale can be operated in a generally contact-free manner.
