The Gill WindMaster Pro is a precision anemometer
offering three-axis wind
measurement data. This instrument will monitor wind speeds of 0-65m/s
and provides
sonic temperature, speed of sound and U, V & W vector outputs at 32Hz as standard.
The unit also features improved vertical (W) resolution and speed of sound accuracy
and less distortion due to wind loading.
Each WindMaster Pro can be calibrated with
an optional Gill wind tunnel test to provide optimum performance.
Optional analogue
inputs and outputs plus a PRT are available with 14 bit resolution.
This anemometer is of stainless steel external construction and is particularly suitable
for precision wind measurement applications requiring 3-axis data involving high
wind speeds.
