In 1954, the solid electrolyte (zirconia) research began in Greifswald, Germany. The "Research Group of Solid Electrolytes" from Ernst Moritz Arndt University of Greifswald was developed new sensor systems in cooperation with industrial users. As a result, in March 1968, the world's first flue gas probe for the optimization of large combustion plants was commissioned in Dresden. Together with scientists of Greifswald University, sensor systems with till then unrivaled parameters have been developed. For many problems (e.g. ceramic firing, surface treatment, float glass production) new methods could be established.
In the beginning of 1990, members of the "Research Group Solid Electrolytes" and the "Scientific Device Construction of EMA University" founded the Zirox - Sensoren & Elektronik GmbH. The company works on new application fields of solid electrolyte sensors in process measuring technology using the knowledge acquired in the research group.
Today, the Zirox GmbH is one of the world's leading manufacturers of high-quality gas analyzers and measuring systems based on solid electrolytes. A number of products have achieved a unique selling position worldwide, e.g. the catalytically inactive potentiometric oxygen-measuring cell. This cell unites the advantages of the conventional high-temperature solid electrolyte sensors and the cold electrochemical oxygen sensors (Clark cells). At presents, approx. 2,500 devices and measuring systems are sold to customers in 68 countries worldwide every year.
