Abstract: A balance including a weighing chamber (16); a draft shield (23), which surrounds the weighing chamber; a climate module (34), which is detachably disposed in the weighing chamber; a processor (32), which is programmed to provide an evaporation rate correction value; a data input unit; and a data transmission path, over which data is exchanged between the climate module and the processor. Also disclosed are a climate module configured to electrically yet detachably couple to a balance, wherein the climate module forms a self-contained modular unit and includes various sensors (52, 54, 62) and a path over which data is transmitted to an external processor, and to a method for calibrating a pipette using a balance, wherein an evaporation rate is determined during the calibration process, and the measurement is corrected in accordance with the determined evaporation rate.
