Calibration of BlowerDoor Pressure Gauges

A measuring service provider, somewhat like a car holder, is responsible for the faultless functioning and the accuracy of the measuring devices used. Ensure the excellent measuring accuracy of our digital pressure gauges, which clearly exceeds the minimum requirements of the European Standard EN 13829, by submitting them to regular adjustment and calibration at our BlowerDoor GmbH premises. It is not necessary to make appointments for the calibration of your pressure gauges. You plan when to calibrate and adjust and we guarantee favorable prices at all times.

The Manufacturer's Calibration

The accuracy of the pressure gauge DG-700 is ±1 %. The working standards applied by BlowerDoor are based on national and international standards. For each differential pressure channel, we calibrate 12 measuring values in the positive and 12 measuring values in the negative range, from ±10 to ±1,220 Pascal.

At BlowerDoor GmbH, the incoming calibration is followed by the adjustment of the pressure gauges 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. The firmware of older pressure gauges is updated free of charge.

The DAkkS-Calibration

Our DAkkS-calibration is conducted according to a standard defined by the German accreditation body (DAkkS). The national metrology institute, Physikalisch-Technische Bundesanstalt (PTB), provides the national standards indicated with the highest possible accuracy. The maintenance of the testing devices, the calibration process, and the organization of the lab are accredited according to German and European Industrial Standard DIN EN 17025. Like all DAkkS-accredited labs, our calibration lab is tested by an internal audit and by DAkkS at regular intervals.

In the DAkkS-calibration of the DG-700 according to procedure A, we calibrate a minimum of 9 points in a measuring range of -1,200 to +1,200 Pa. If requested by the client, we can measure more points. The calibration cycle is repeated four times.

All our DAkkS-calibrations include a functional test and the adjustment of the measuring device. The firmware of older DG-700 devices will be updated free of charge.

The manufacturer recommends the following calibration intervals

  • DG-700: 2 years
  • APT: 1 year
  • Analog pressure gauges: 2 years

Upgrade during calibration: Cruise Control Feature

Since spring 2008, all DG-700 pressure gauges feature a Cruise Control function for automated one-point measurements without connection to a computer. This is ideal for an initial analysis and quality assurance of the airtight building envelope during the construction phase.
Contact us if you would like to add the Cruise Control feature to your DG-700. We will upgrade your equipment during the calibration check at an additional charge.
