The WindMaster Pro 3D ultrasonic anemometer will monitor wind speeds of 0-65 m/s (0-234 km/h), providing digital outputs for U, V, and W vectors. Outputs for Speed of Sound and Sonic Temperature are available as standard. WindMaster Pro is constructed of stainless steel and is available with 32 Hz data output rate. Optional analog inputs and outputs are available with 14 bit resolution. A Platinum Resistance Thermometer (PRT) input is an order option. This 3D ultrasonic anemometer is ideally suited to the measurement of air turbulence around bridges, buildings, wind turbine sites, building ventilation control systems, meteorological and flux measurement sites.
