ExTox Gasmess-Systeme GmbH

We founded ExTox Gasmess-Systeme GmbH in Dortmund in 2004. Due to rapid growth right from the early days the number of collaborators grew constantly, and this is why we moved to bigger and more comfortable installations in nearby Unna. We plan and manufacture Gas Measurement Systems and develop the necessary electronic components as well as software or housings by ourselves. We sell our products all over the world, and we provide after-sales service such as the initial start-up, maintenance or repairs in Germany as well as in other countries.
