Calibration of BlowerDoor Fans
NEW: Manufacturer's calibration (1-point)
We offer manufacturer's calibration (1-point) for the measuring fans BlowerDoor Standard (model 4) and BlowerDoor MiniFan (model DuctBlaster) according to the manufacturer's specification. One measured value is calibrated per measuring ring (open fan as well as ring A - E or 1 - 4). The requirement of ISO 9972 (measuring accuracy ± 7 %) is assessed. You will receive a calibration certificate.
A previous basic maintenance and functional test is included. We calibrate according to your appointment request. Your registration is desired to ensure short calibration times of max. five working days.
Recommended calibration interval: 4 years
Calibration with DAkkS certificate
We offer a calibration with DAkkS certificate for the measuring fans BlowerDoor Standard (model 4 and model 3) as well as BlowerDoor MiniFan (model DuctBlaster) on our test stand calibrated by the Physikalisch-Technische Bundesanstalt. For each measuring ring (open fan as well as ring A - E or 1 - 4) three measured values are calibrated. The measuring accuracy of the BlowerDoor measuring fans of ± 4 % (open fan as well as rings A - C or 1 - 4) and ± 5 % (rings D and E) is assessed. You will receive a DAkkS certificate.
The previous basic maintenance and functional test is included. We calibrate according to monthly calibration dates. Registration is required.
