METTLER INSTRUMENT COMPANY
Richard A. Paselk
The Mettler balance company was founded when Erhard Mettler (1917-) determined around 1945 that there was an opening for a new kind of balance. All of the indeividual characters of this new balance had already been invented and used in past instruments, what Mettler did was combine them in a new and more effective manner. The success of his new balance and company were also aided by the destruction of much of the balance industry of Europe during WW II, and their slow recovery afterwards.
Mettler's new mechanical substitution balance, developed with the aid of Hans Meier (1914-) an experienced Swiss instrument engineer, incorporated all of the essential features upon its introduction in 1947:
All of these features, in their final conformation may be seen in the scan of the Mettler poster, The Modern Analytical Balance.
In 1955 Mettler introduced the first top Loading scale with optical readout. This balance also incorporated the first dial controlled taring. The top loading precision balance line quickly gained wide acceptance, soon occupying nearly half of Mettler's production.

Vendor Catalog Scans
As a supplement information above, a collection of scanned images and descriptions of balances is available via the table below.
The images and catalog descriptions are scanned from vendor catalogs in the curator's collection. In each case an effort has been made to scan all of the balances of a given manufacturer in the catalog. It should be noted. however, that the distributors generally show only a selection of balances from any one manufacturer. Catalogs are selected from the curator's collection at approximately ten year intervals, when available, with a second criteria being representation of the specific manufacturer. In the case of Mettler, the first two catalogs, though only three years apart, document a significant change in the distribution of Mettler balances in the United States, so both are included.
