Description
Overview
GAOTek Ultrasonic Anemometer With Wind Direction has advantage of robust, no moving parts, free of maintenance and calibration on site. Simultaneously output wind speed and direction and it can be used in conjunction with a PC, data logger or other device, which has compatible communication protocol with it.
