The Gill WindSonic™ is a low-cost 2-axis ultrasonic anemometer, providing wind speed (0-60m/s) and direction data in a robust housing. This anemometer has no moving parts, offering maintenance-free operation in a wide range of applications.

The Gill WindObserver™ range consists of 2-axis ultrasonic anemometers offering wind speed (0-75m/s) & direction data in robust stainless-steel housings. The range includes: Intrinsically Safe approval; High Heating Power; FAA Approval.
The Gill WindMaster™ range of 3-axis ultrasonic anemometers provide wind speed (0-45m/s and 0-65m/s) and direction (0-359º) data. 3-vector outputs are available (U, V, W), along with speed of sound and sonic temperature outputs.
The Gill R3™ range of 3-axis ultrasonic anemometers is particularly suited to Eddy Covariance analysis. R3™ anemometers are available with 50Hz or 100Hz output rates and will provide U, V, W vector, Sonic temperature & speed of sound outputs.
The Gill HS™ ultrasonic anemometer range offers the same specification levels as the R3 range, with a 3-axis horizontal mount that reduces airflow interruption from the anemometer geometry.
