About us

In 1991 the GSA Messgerätebau GmbH was established and was continued 2015 by Brigitte Tomaschewski und Peter Kunzendorf in Ratingen.

Our company arose from the, in professional circles well known, GSA Gesellschaft für Schadstoffanalytik mbH, who collaborated to set many national and international standards of dust measuring techniques.

We look back at decades of expertise for the construction of special measuring devices for measurement of workplaces, emission- and immission measurements

About 40 percent of all DAX Members are our customers. They appreciate our sophisticated technique of measurement and possibilities for measurements of pollutants. 

Our expertise goes directly into the development of efficient measuring devices with modern standards for the stationary or mobile use in order to increase the safety at work and improving housing standards.

In addition to inhouse-productions we built devices for measurement of workplaces that were developed by the Institute for Occupational Safety of the Deutschen Gesetzlichen Unfallversicherung (DGUV) under licence.

With our comprehensive field experiences we implement our findings for our users.

We create high-quality sampling devices and sample carrier systems for the measurement of dusts, gases and steams.

Our products are made in Germany. Moreover we hold a TÜV certificate according to ISO 9001:2015.

Our GSA mearsuring devices have the following advantages: 
•    compactness
•    low height
•    operational safety

The GSA Messgerätebau GmbH is managed at the same location as the GSA Gesellschaft für Schadstoffanalytik mbH. The GSA Gesellschaft für Schadstoffanalytik has an over 30-years experience in advising on questions and problems of harmful substances. Moreover the company has expertise in the sampling of materials with suspicion of harmful substances and in the analysis and assessment of harmful substances like asbestos, inorganic fibres and dusts.
