Certification of measuring instruments according to ISO17025

The high accuracy of our measuring instruments for air-flow and micro pressure is granted by comparison with references with an even appreciably higher precision. For air-flow this is an ultra-precise Laser-Doppler-Anemometer (LDA) in a specially developed wind-tunnel. A measuring uncertainty is resulting of +/- 0,5 % (minimum 0,01 m/s).

The comparison of our micro manometers with a high-precision reference source is done in a laboratory where relative humidity, temperature and barometric pressure are continuously monitored. The instruments under test and the reference source have exactly the same barometric height. A measuring uncertainty of +/- 0,02 % (minimum 0,1 Pa) is resulting.

  • Precision measuring of air-flow and micro pressure
  • Measuring range for air velocity 0 … 65 m/s, for pressure 0 … 25 kPa.
  • For each ISO17025 certified instrument an own calibration certificate is given out.
  • We are accredited under the number SCS046 by Swiss Accreditation Service (SAS) who are member of ILAC (International Laboratory Accreditation Cooperation). This is guaranteeing the acknowledgment of our measuring device as a reference in more than 130 countries.
