Functional test and adjustment included (APT2, APT4, APT6 and APT8). The accuracy of our digital pressure gauge APT is ≤ 1% (0 - 800 Pa) respectively ≤ 2%  (800 - 1000 Pa). The working standards applied by BlowerDoor are based on national and international standards. For each differential pressure channel, we calibrate 20 measuring values in the range from ± 1,000 Pa. At BlowerDoor GmbH, the incoming calibration is followed by the adjustment of the pressure gauge so that deviation errors can be corrected as necessary. The outgoing calibration documents the optimized measuring accuracy of the adjusted pressure gauge. The preceding functional test also checks the tightness of the pressure sensors, the control of the BlowerDoor fan, and the overlay. Recommended calibration interval: 1 year.
