Precision balance with improved immunity to temperature and pressure variations

摘要

Slots are provided in at least one wall or surface common to the weighing chamber and the chamber housing the weighing mechanism. These slots are located so that air currents streaming through them will not affect the weighing dish and thereby the measured results. The slots are preferably located in the bottom near the front wall or the rear wall of the weighing chamber. The air currents can then effect rapid temperature and pressure compensation.
