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).
