- Measurement Systems for Airtightness
Ensure the high precision of BlowerDoor measurement technology through regular calibration. Both the factory calibration and the calibration with DAkkS certificate are subject to high quality standards at BlowerDoor. Upon request, we will provide you with a replacement measuring device for the duration of the calibration or in case of repair.
In addition to the very high quality manufacturer's calibration, BlowerDoor GmbH, as an accredited laboratory according to DIN EN ISO/IEC 17025, has also been offering calibrations with DAkkS certificate for the pressure measuring devices since April 2015. The extensive investments in the accreditation of the in-house calibration laboratory were made in order to meet the increasing requirements of national and international standards.
Part of both the manufactuer's calibration and the calibration with DAkkS certificate is a preceding basic maintenance and functional test as well as the adjustment of the pressure measuring instruments.
Since January 2015, BlowerDoor GmbH has been calibrating the BlowerDoor measuring fans on a specially designed and implemented test stand, which has been calibrated by the Physikalisch-Technische Bundesanstalt (PTB) with an accuracy of ± 1%. This accuracy is required to confirm the conformity of the measuring system up to ± 4% (rings A - C and rings 1 - 4) or ± 5% (rings D + E). In August 2017, this calibration stand received a DAkkS accreditation.
As an alternative to the calibration with DAkkS certificate, we also offer manufacturer's calibration (1-point) according to manufacturer's specification from April 2023. Before each fan calibration, a basic maintenance and a functional test is carried out first.
