Favorite
HD2003 and HD2003.1 are three axis ultrasonic anemometers, they measure the speed and direction of wind, the U-V-W Cartesian components of speed, wind gust, sound speed and sonic temperature. 

The HD2003 allows also to detect temperature and relative humidity of the air and barometric pressure.
