Abstract
An analytical balance that includes a balance scale, a wind guard encircling the balance scale, and an apparatus for generating an ionized stream of air for dissipating electrostatic charges of goods to be weighed. The apparatus for generating an ionized stream of air includes a blower that draws in air from the weighing space into at least one boundary surface of the weighing space. The blower also recycles the air back into the weighing space via at least one exhaust opening at another point. In this manner, highly effective dissipation of electrostatic charges is possible, and the stream of air can be conducted so that it exerts scarcely any vertical forces on the goods to be weighed. The analytical balance is very user-friendly in operation. Additionally, the apparatus for generating an ionized stream of air is preferably structured to be an easily installed optional component of the analytical balance.
