Wind Tunnel Calibrations Services

With our CSIRO designed wind tunnel situated at our Melbourne head office, we are the only NATA / ISO 17025 accredited laboratory in Australia that can calibrate all types of anemometers.

ypical users of our calibration services include:

  • Environmental protection authorities
  • HVAC industry
  • Mining industry
  • Construction companies
  • Environmental researchers
  • Wind energy organisations

We calibrate all makes and models of conventional vane, hot wire, cup, propeller and ultrasonic anemometers as well as Pitot-static tubes and Pitot-static tube anemometers. Low and high speed calibrations are available, as well as wind direction.

Low Speed Test

Calibrations are performed in the range 0.30 to 15 m/s. Our measurement uncertainty is ±0.05 m/s or ±1% (whichever is greater) at a 95% confidence level with a K coverage factor of 2 unless otherwise stated.

High Speed Test

Calibrations are performed in the range 0.30 to 30 m/s. Our measurement uncertainty is ±0.05 m/s or ±1% (whichever is greater) at a 95% confidence level with a K coverage factor of 2 unless otherwise stated.

Wind Direction Test

Calibrations are performed at each 30 degrees using a mechanical dividing head at a nominal wind speed of 6.0 m/s. Our measurement uncertainty is ±2 degrees at a 95% confidence level with a K coverage factor of 2 unless otherwise stated.
