Abstract: A precision balance including a weighing chamber (16); a draft shield (18, 20, 22), which surrounds the weighing chamber (16); a climate module (34), which is detachably disposed in the weighing chamber (16); a processor (32) and a data input unit, which both form part of the overall precision balance; and a data transmission path, over which data is exchanged between the climate module (34) and the processor (32). Also disclosed is a climate module for a precision balance. The climate module (34) forms a self-contained modular unit and includes an air pressure sensor (62), an air humidity sensor (54) and an air temperature sensor (52) The climate module also includes a data transmission path configured to transmit data to a processor external to the climate module, and a mounting mechanism configured to secure the climate module detachably to a weighing module (10).

Abstract: A mass comparator including a weighing chamber (16); a draft shield (18, 20, 22), which surrounds the weighing chamber; a climate module (34), which is detachably disposed in the weighing chamber; a processor (32), a data input unit, and a data transmission path, over which data is exchanged between the climate module and the processor. The processor is programmed to use the air pressure, the air humidity and the air temperature in the weighing chamber to determine, based on the density of a substance to be weighed, an air buoyancy of at least one test sample and/or a buoyancy correction factor. Also disclosed are a climate module configured to electrically yet detachably couple to a mass comparator, and a method for operating a mass comparator including determining the air buoyancy and/or the buoyancy correction factor.

Abstract: A balance with a load changing device (14) that has a magazine table, mounted to be horizontally movable and having a plurality of vertical openings (26) arranged in groups. The balance (12) has a load cell (34) and a load receptor (42) with a carrier arrangement (44) corresponding to each of the groups of openings. The magazine table and the balance are height adjustable relative to each other. In a weighing position, a group of openings above the load receptor is penetrated by the carrier arrangement. In a changing position, the carrier arrangement is positioned lower than the openings in the magazine table. The magazine table is mounted at a fixed height relative to a base (16), and the balance is height adjustable relative to the base. The travel of the balance is upwardly limited by a stop (32), which is at a fixed height relative to the base.
