DAkkS accredited calibrations:
Our calibration laboratory is equipped with the latest measurement technology and meets the requirements of DIN EN ISO 17025.
We offer calibrations for the measurands flow velocity and volume flow rate of gases (air).
You can rely on us to calibrate your measuring instruments carefully and to the highest standard, thus ensuring that your measuring instruments function perfectly.
Our scope of accreditation includes:
Measurement quantity/ Calibration item | Measurement range | Measurement conditions / procedure | Expanded unvertainty | Remarks |
| 0.1 m/s to 40 m/s | Calibration of Anemometer in wind tunnel | 0.5 %, but not less than 0.01 m/s | Wind tunnel Göttinger type, nozzle: 255 mm | |
| Flow velocity of gases (air) Anemometer | 0.1 m/s to 70 m/s | Calibration of Anemometer in wind tunnel | 0.5 % but not less than 0.01 m/s | Wind tunnel Göttinger type, nozzle: 180 mm |
| 0.5 m/s to 45 m/s | Calibration of Anemometer in wind tunnel | 0.7 %, but not less than 0.05 m/s | Wind tunnel Göttinger type, nozzle: 800 mm | |
| Volume flow rate resp. volume of flowing gases (air) | 80 m³/h to 4,300 m³/h | Calibration of volume flow devices at volume flow test bench | 1,5 % of reading value | Reference standard: inlet nozzles Differential pressure method |
If you would like a non-accredited calibration service, please note that the report is not an accredited report and is not covered by the EA MLA.
ISO-Calibrations:
Furthermore, we also offer factory calibrations that include differential pressure, temperature and relative humidity in addition to flow velocity and volume flow.
Our engineers ensure that your measurement equipment can perform the functions you need.
Our scope of ISO-calibration includes:
Measurement quantity/ Calibration item | Measurement range | Measurement conditions / procedure | Remarks |
Flow velocity of gases (air) Anemometer
| 0.3 m/s to 40 m/s | Comparative measurement of flow velocity in the wind tunnel | Reference standard: Traceable thermoelectric anemometer Wind tunnel |
| Volume flow rate resp. volume of flowing gases (air) | 20 m³/h to 4,600 m³/h | Calibration of volumetric flow meters on the volumetric flow test rig | Reference standard: inlet nozzles Differential pressure method |
| Differential pressure | 0 to 100 kPa | Comparative measurement of differential pressures | Reference standard: Differential pressure transmitter Pressure calibrator |
| Temperature | -10°C to 100°C | Comparative measurement of temperatures | Reference standard: electrical thermometer Block temperature calibrator |
| Relative humidity | 10 to 95 % | Comparative measurement of relative humidity | Reference standard: electrical hygrometer Humidity generator |
