The COMDE GmbH was founded in Berlin by graduate engineer Norbert Derenda in 1993. It was originally set up as COM GmbH, a private limited company, with the objective of solving metrology assignments and implementing computer-assisted assessment of measured data. In 1998 the company was reorganized as COMDE GmbH (computer-oriented metrology, design and engineering).

 

The introduction of a reference-quality gas density monitor followed in 2000. This advance was based upon a temperature-compensated, pressure-actuated switch which had been devised by Norbert Derenda 24 years earlier, in 1976.

 

Once the production of this gas density monitor had been launched, the company decided in 2001 to relocate to more spacious facilities at an industrial building situated in the town of Teltow, near Berlin. The sales and production lines were then expanded to include additional mechanical and electronic gas density monitors. Today the range includes not only those gas density monitors but also a large number of pressure transducers, mechanical and electronic pressure-sensitive switches and pressure sensors for elevated pressures and temperature. These are used, for instance, to measure pressure in oil and gas exploration and in geothermal applications. Pursued in parallel was the development of hardware and software for a wide variety of measurement and surveillance tasks.

 

Then, in the year 2000, the company was certified as per ISO 9001:2000.

 

Building upon the remarkable business success and the resultant expansion of production, the company erected its own, modern, purpose-built manufacturing building and took occupancy in July of 2007.

 

Ever since 1972 Norbert Derenda, the proprietor of COMDE GmbH, has also headed up an engineering office which is now located in the same building. That engineering office devotes its efforts to the development, production and sales of devices used to collect and measure particulate matter in outdoor air; some of the designs created here are reference units. The line offered by that company can be seen at a separate website, at www.derenda.de.
