Abstract

A gravimetric measuring device includes a weighing chamber with a vertical weighing chamber wall, which is formed as a support structure (14) with cover modules (28) detachably fixed thereto on the weighing chamber side, each cover module (28) having, on its weighing chamber side, a module front wall (30) covering the support structure (14) at least partially. The cover modules (28) have locking cantilevers (38) directed towards the support structure such that the locking cantilevers (38) are provided with vertically directed through-openings (40) which are aligned with corresponding through-openings (20, 22) of the support structure (14). The cover modules (28) are locked to the support structure (14) with locking rods (42) which pass through the mutually aligned through-openings (40; 20, 22) of the cover modules (28) and the support structure (14).
