The WindMaster Pro is constructed from stainless steel and has a maximum operating wind speed of 65 m/s. With a fast maximum data output rate of 32 Hz as standard, improved vertical (W) resolution and Speed of Sound accuracy and less distortion due to wind loading, this 3-axis anemometer is particularly suitable for precision wind measurement applications requiring 3-axis data.

Optional analogue inputs and outputs plus a PRT are available with 14 bit resolution.
