From the electrode to the fully automatic measuring system – Innovation is always lived here

On April 13, 1973, the company SCHOTT-Geräte GmbH was founded in Hofheim, Germany, as a subsidiary of the former SCHOTT Glaswerke, now SCHOTT AG, in Mainz. The company, located in the Taunus region, focused on the production of pH electrodes and glass capillary viscometers. In order to open up new markets, the product portfolio was expanded to include automatic pH meters in 1974 and viscosity meters in 1975. In 1978, titration products were introduced.
After the company moved in 2001 from Hofheim to its current headquarters in Mainz, SCHOTT-Geräte GmbH became SCHOTT Instruments in 2003 through an acquisition of Nova Analytics. Even then, the company was a pioneer in Europe with its range of digital analytical measurement technology.

In 2009, SCHOTT Instruments became SI Analytics®. SI stands for the main products sensors and instruments, and the addition of Analytics represents one of the core competencies, namely the manufacture of analytical instruments.

Today, SI Analytics® is a brand of Xylem. More than 130 employees work at the Mainz site in the areas of production, development, sales, application, product management, warehouse and shipping.
