The WindMaster HS 3D ultrasonic anemometer will monitor wind speeds of 0-45 m/s (0-162 km/h), providing digital outputs for U, V, and W vectors. Outputs for Speed of Sound and Sonic Temperature are available as standard. Optional analog inputs and outputs are available with 14-bit resolution. A Platinum Resistance Thermometer (PRT) input is an order option. WindMaster HS is constructed from stainless steel in a unique horizontal head design which allows for accurate measurement with minimum flow interruption.
