ABSTRACT:
A precision balance including sliding side doors and an upper cover forming the weighing chamber of the balance. The side doors and the cover can be moved individually or coupled together either manually or driven by a motor. Side parts of the support member form the connection between the side doors and the upper cover. In addition, the side doors are connected to each other by means of a plate extending underneath the weighing chamber and the balance housing. The connection between the movable parts is effected by means of sliding bolts provided in handles. The individual sliding bolts facilitate a coupling between the sliding side doors and/or the cover. The plate extending under the weighing chamber facilitates a connection of the two side doors so that the latter can be moved simultaneously either with or without the upper cover.
