For over 55 years, we have been developing, manufacturing, and supplying practical systems and instruments worldwide for measuring meteorological parameters. Our cooperation with scientific institutions and organisations internationally guarantees an up-to-date flow of information on individual national problems, projects and rapid implementation of state-of-the-art developments, and measurement techniques. Our instruments, systems, and software fulfil in all respects both for national weather services as well as the World Meteorological Organization. Certification of our quality management system acc. to DIN EN ISO 9001:2000 guarantees our high quality standard and continuous improvement of our products. With the expansion of our test laboratory, and new wind channel (Goettingen design) we offer and carry out temperature, humidity, precipitation, air pressure and wind speed calibrations for highest requirements. Our quality standards for calibration processes meet international standards. Our calibration certificates are made out acc. to DIN resp. DIN EN ISO 9001:2000. As a supplier of environmental measurement instruments we feel particular constrained to protect the environment in all our activities. This approach is now officially approved by the DIN ISO 14001:2005 certified Environment Management System.
