Odournet – accredited calibration laboratory for dilution units

Odournet GmbH has received accreditation for their calibration laboratory according to ISO 17025 for calibrations of dilution units for gas samples (e.g. olfactometers) under registration number D-K-17433-01-00 by the German accreditation body DAkkS.

This accreditation confirms the quality of our calibration services and is the formal recognition that our laboratory is competent to calibrate EN 13725 accredited dilution units for gas samples according to ISO 17025. This includes both, dilution units with orifice systems and those with mass flow controllers in the range 1 to 100,000 (dilution number Z).

Odournet GmbH is the only German and one of the few ​accredited calibration laboratories in Europe for this scope.

All measurement data is traceable to SI units and is internationally recognized. Since this traceability of measurement data to national/international standards is often required for ISO 17025 or ISO 9001 audits, we are happy that we can supply a valuable contribution to the documentation of your laboratory quality by issuing calibration certificates according to ISO 17025.


The calibration laboratory of Odournet GmbH is an independent and DAkkS-accredited calibration laboratory. The accreditation indicates the competence of a conformity assessment body in accordance with international standards. In addition, our calibration laboratory is member of the German Calibration Service (DKD).
