WEATHER STATION The YOUNG ResponseONE Ultrasonic Anemometer accurately measures wind speed and wind direction without moving parts. The IP66 rated construction includes an integrated compass to enable mobile applications. Standard digital serial output formats provided include SDI-12, NMEA, and ASCII text. Output may be continuously provided or, to conserve power, polled output may be used. RS-232 or RS-485 serial format options enable direct integration with YOUNG displays, marine NMEA systems, data loggers or other compatible serial devices. The ResponseONE features durable, corrosion-resistant construction and installs on readily available 1 inch (IPS) pipe. Wiring connections are made in a convenient weather-proof junction box. Special connectors and cables are not required.
