Calibration of the BlowerDoor Measurement Systems

Benefit from the expertise of BlowerDoor GmbH

Maintain the high accuracy of your BlowerDoor measuring technology by regularly submitting it to a manufacturer’s or DAkkS-calibration. Benefit from the high accuracy of the BlowerDoor measuring technology: At ± 4% or rather ± 5% (flow rings D + E), the accuracy of the BlowerDoor testing flow rings – as well as that of the pressure gauge DG-700 (± 1%) – clearly exceed the minimum legal requirements. The manufacturer’s calibration as well as the DAkkS-calibration, are subject to the highest quality standards. When calibrated, all measuring systems undergo a preceding functional test. If required, we will gladly provide you with a replacement device at favorable rates and conditions, while your BlowerDoor measuring system is being calibrated or repaired.

  • Multiple-point calibration ensure the highest accuracy
  • Individual calibration of your pressure gauges and BlowerDoor measuring fans
  • Short calibrating times, easy handling, attractive price

Manufacturer's calibration and DAkkS calibration of your pressure gauges

In addition to offering high-quality manufaturer's calibration, BlowerDoor GmbH has been a DAkkS-accredited lab since April 2015, and as such, also offers calibrations in accordance with DIN EN ISO/IEC 17025 with a DAkkS certificate for the DG-700 pressure gauges. The substantial investment in the accreditation of our calibration lab was made in order to meet the increasingly stringent requirements of national and international standards. Both calibrations, the manufacturer's and the DAkkS calibration, include an adjustment of the pressure gauges.

Manufacturer's calibration and DAkkS calibration of your BlowerDoor fans

We calibrate all BlowerDoor measuring fans using a test stand designed and implemented by BlowerDoor GmbH, which has been calibrated by the Physikalisch-Technische Bundesanstalt (PTB), Germany’s national metrology institute, with an accuracy of ± 1%. This level of accuracy is necessary in order to attest conformity of the measuring fan of up to ± 4% (rings A - C) respectively ± 5% (rings D + E). In August 2017 this calibration stand has been accredited by DAkkS (Deutsche Akkreditierungsstelle GmbH).
