Abstract: A dosing device with a balance, which includes a weighing chamber (16); a processor (32); a climate module (34), which is disposed in the weighing chamber (16); a data transmission path, over which data is exchanged between the climate module (34) and the processor (32); and a mixing formulation display (30). Also disclosed are a climate module configured to electrically couple to a dosing device in a detachable manner, wherein the climate module (34) forms a self-contained modular unit and includes various sensors (52, 54, 62) and a path over which data is transmitted to a processor external to the climate module, and a method for mixing a formulation, using a dosing device, wherein ambient conditions are detected during dosage of the substances to be combined, and the mixing ratio is adjusted in accordance with the detected ambient conditions.

Abstract: An electronic scale (1) with a display unit (9), at least one control button (11 . . . 14), a digital signal processing unit (5) and a digital interface (7) to a higher-level electronic data processing (EDP) system (15). The digital signal processing unit (5) has an activatable switch or program part for locking the scale. This switch or part releases the display of the weighing result only for as long as the higher-level EDP system (15) communicates with the scale (1) and locks the display at other times. The activation of the switch or part for the locking process is stored in a power-failure-proof memory (21).
