E+E Elektronik has been commissioned by the BEV (Austrian Federal Office of Metrology and Surveying) to provide the national measurement standard (etalon) for CO2 gas concentration. The E+E calibration laboratory has been entrusted with this important task for humidity and dew point since 2004, and for air velocity since 2011. In April 2021, the designation for CO2 gas concentration was also granted.
This makes the calibration experts from Engerwitzdorf the highest metrological authority in the country for a physical quantity further to the aforementioned. As a BEV’s designated institute, E+E Elektronik is authorized to perform special calibrations at the level of a national metrology institute.
As a designated institute, E+E Elektronik is committed to maintaining and further developing the national etalons in accordance with the current state and requirements of metrology. The prerequisite for this, in addition to the necessary metrological expertise and equipment, is a stringent quality management system in accordance with EN ISO/IEC 17025. In addition, E+E Elektronik is subject to regular monitoring audits by the BEV and international calibration experts.
To ensure the equivalence and international recognition of national etalons, E+E Elektronik participates in key comparisons by the CIPM/BIPM (Comité International des Poids et Mesures / Bureau International des Poids et Mesures) or EURAMET (European Association of National Metrology Institutes). Furthermore, E+E Elektronik is represented on international committees in the field of metrology for the pertinent physical quantities.
According to the CIPM Mutual Recognition Arrangement (MRA), E+E Elektronik is entitled to show the CIPM-MRA logo on its BEV/E+E calibration certificates. Calibration certificates from institutes that have this logo enjoy the highest level of acceptance and are of particular interest to accredited calibration bodies due to their association with a National Metrology Institute.
“The fact that we are now also a designated institute of the BEV for CO2 gas concentration, following humidity, dew point and air velocity, delights us. It further demonstrates the great expertise of our calibration laboratory, something that our customers have been benefiting from for years,” says Dietmar Pachinger, Head of the E+E Calibration Laboratory.
Accredited Calibration Laboratory
In addition to special calibrations as a designated institute, E+E Elektronik also offers accredited measuring device calibrations for the physical quantities humidity, dew point, CO2, air velocity, air flow, temperature and pressure. To this end, E+E Elektronik is accredited as a calibration laboratory according to EN ISO/IEC 17025 under identification number 0608 by the Austrian National Accreditation Body/Federal Ministry for Digital and Economic Affairs. The decisive feature of accredited calibrations – in contrast to so-called ISO or in-house calibrations – is the traceability of the measurement results to a national standard and thus their international comparability.
The Austrian sensor manufacturer and calibration expert E+E Elektronik has been commissioned by the BEV to provide the national measurement standard for CO2 gas concentration.
