The design of WindMaster HS three-dimensional ultrasonic anemometer meets the scientific research requirements for accurate three-dimensional wind speed, wind direction, and ultrasonic temperature measurement data.
WindMaster HS adopts advanced ultrasonic measurement technology and a unique transverse measuring head design, which enables the ultrasonic anemometer to minimize the interference of the instrument's physical structure on the airflow when measuring at high angles of attack.
Integrated electronic component technology provides four optional analog input and output interfaces for the instrument.
