Our wind tunnels are among the world's most accurate and are specifically designed for the calibration of anemometers and wind vanes. All of our wind tunnels are of the Göttingen-type (closed circuit, total length 38m). Measurements can be performed using both open and closed test sections. The test section measures 1.2m x 1.2m x 1.8m, and is ideal for the precise measurement of wind measurement sensors.
