Resumo: This work intends to describe the historical evolution of the balance based on its technical improvement. This instrument has always been used for commercial and industrial purposes, but its value in research and chemistry was only recognized much later. The classical balance was the two-pan model for about 40 centuries, but when its importance in chemistry was established, particularly beginning at the end of the XVIIIth century, many improvements were made in order to increase sensitivity and shorten the weighing procedure. The balance design greatly changed along the XXth century: the classical two-pan models were replaced by one-pan balances that were replaced by electronic instruments.
