Mettler-Toledo International history

Large-scale production of the unit began in 1946.

Mettler continued to refine its technology, introducing, in 1952, the Mettler Mikrowaage ("Microscale"), capable of measurements to 0.000001 grams.

In 1955 Mettler introduced the first top Loading scale with optical readout.

In 1962 the company acquired Doctor Ernst Rüst AG, a maker of high-precision mechanical scales, which had been founded just three years before.

The newly added division would be renamed as Mettler Optic AG. Mettler also made its first moves at expanding its product categories, introducing a thermal-analyzer, the TA 1, in 1964.

In 1965 Mettler opened a new assembly facility, in Uznach, which initially employed just three people for the assembly of the company's precision balances.

The FP line was joined by the TM line of temperature analysis instruments, introduced in 1968, as well as the PE line of precision balances, the company's first scales to incorporate emerging electronic technology.

In 1973 Mettler debuted its PT1200 scale, the industry's first fully electronic precision balance.

The new balance proved immediately successful upon its official 1974 launch.

In 1980 Mettler's shares were bought up by Swiss giant Ciba-Geigy.

Next, in 1987, Mettler took over Garvens Automation GmbH, near Hanover, Germany, and that company's dynamic checkweighers, dosage control, and other processing systems.

In 1989 Mettler acquired the Toledo Scale Corporation, based in Worthington, Ohio.

By then, Mettler-Toledo had elected a new company chairman, Robert Spoerry, who had been serving as company CEO since 1993.

In 1996 Mettler-Toledo regained its independence from Ciba-Geigy after a management buyout, assisted by AEA Investors, a New York-based investment group, worth US$402 million.
